As microcontrollers are essentially low performance computers on a chip they have a processor, RAM and ROM they can be used to create small computer systems. Note this PCB is dual layer. The circuit diagram and the PCB were created in the program Fritzing. An interrupt pin must be used for the keyboard clock line meaning pins 2, 10 and 11 can be used as the clock pin on the P; I chose to use pins 10 and 11 for the data and clock lines of the keyboard.

An LED was also included onboard to indicate if the shield was being powered. Two other headers are onboard to allow connections to the power pins 5V and GND and to allow the serial communication between the P and the UNO to be connected to. The image shows the circuit diagram with an ATmega the P and are pin compatible and the Fritzing project file and circuit diagram PDF can be found attached as a RAR archive.

Once the PCB had been designed in the Fritzing program, it was sent to a PCB manufacture to be produced using the isolation milling process. I designed the PCB to be double sided to reduce the number of jumper parts needed and to make the PCB designing process simpler it would be harder to keep the PCB single sided due to its small size.

Also, through hole plating would be needed to keep the PCB single sided as the pin headers need to be soldered on the top side. As the PCB production process does not have through hole plating, I had to use vias to jump between layers. A small piece of tinned copper wire is placed in the via hole and soldered on either side to make a connection between the top and the bottom layers. To reduce the number of components in the circuit, no crystal was used as the Ps clock source, instead its internal 8MHz oscillator is used.

One of the images shows a copper coloured PCB. This is a manufacturing reject board as the PCB manufacturers milling machine did not produce this board correctly the holes are slightly out. The reason this board is copper coloured is because it is not tinned.

The tinned PCB was correctly produced and used to create the shield. Note, the PCB could also be optimised in various ways. Without alterations, TinyBASIC uses the serial port for user interaction meaning it needs to be altered to read the keyboard input instead of the serial input. To do this, all calls to "Serial. It may be possible to also include the serial reading communications to allow any device connected to the serial header to interact with TinyBASIC but it is currently removed.

Serial transmission code was left alone as there was no need to change it the Arduino UNO reads the serial output of the P and prints to a TV. Both sketches can be found attached as a RAR archive.

Once the PCB had been designed and manufactured, it was soldered and tested. One issue which arose was serial communications from the P were not being received by the Arduino UNO. Once the short was fixed, the shield operated correctly. Thank you for taking the time to read my instructable. Any feedback is appreciated. Update: I have been informed it is not possible for the Arduino Mega to output the resolution of x This means the second version of this shield if it was based on an Arduino Mega would possibly allow higher RCA resolutions due to the higher SRAM compared to the Arduino UNO but it will not allow the resolution of x to be produced.

Greetings from the middle of the Mohave Desert! Right now I am running tiny basic on a little nano but I would really love to have a stand alone little basic computer like this to use. I would hook her up to an old flat screen TV or my backup monitor I removed from my old Motorhome when I traded her in for my current one that has a built in rear camera and monitor. Very well made project, as well as product.

I was wondering at perhaps porting the whole thing to a Due with it's increased processor power and memory?

Can someone please give me a link to download tiny basic I can not find a site that will work on mine.Hello again, students, to my second lesson of my course to teach basic electronics. For those who have not seen my first lesson, which describes the very, very, basics of circuitry, please see that now.

For those who already have seen my previous lesson, let us begin. To start off this lesson, let us start with asking: what is this strange blue device you see on your screen? The answer is an arduino.

I will define to you what Arduino is in a single statement: Arduino is a chip which is the master and manipulator of all circuits that connect to it. This seemingly simple chip is the very basis of several complex projects constructed world-wide, and yet is simple enough to program that even children can easily learn how to use it.

Okay, okay, before you start breaking a sweat about not knowing what half of what I will say will mean, just know that today's lesson is just comparing certain parts of Arduino with that of a basic circuit.

Don't worry, I am not eating any steps here. For those who have seen my previous lesson, this color coded version of the diagram should seem familiar. Red represents power, blue the ground and green are pins that are connected to a power.

The Grey box seen above the Arduino is a power source or battery of any kind. However, this lesson will not focus on the green pins coming from the Arduino. Instead, we will be focusing on doing what we did in the last lesson which was lighting up an LEDexcept we will be using an Arduino as a power source. Before you make your connections, I would like to bring up some details about which pins from the Arduino Uno to use.

Looking at the regular diagram of the Arduino, you should see 2 important names: 5V and gnd. These are what you will be using as your power and ground terminals. Gnd is an abbreviation for ground, so use any of the three pins on Arduino labeled gnd as your ground. Also, for some electrical safety, be sure to know the following: The LEDs you see on the diagram of your list of components have an observable feature: one leg is longer than the other. When connecting LEDs in circuits, make sure that the longer leg is connected to the power side and the shorter leg to the ground side.

If you switch the legs, your circuit will not work. For the power, connect the wire anywhere on the horizontal red rail the rails are labeled, red being power and blue being ground and for ground, connect a wire from it to anywhere on the blue rail. Your one LED should light up brilliantly.

This works because the electricity flowing out of the short end of the first LED is almost like as if the first LED is an extension of the Power rail.

Circuit Diagram Maker software

But, like connecting the first LED, this electricity has to go to the long leg of the second LED, or else the circuit won't be complete. Repeat this procedure until you are on the last LED. Those who've seen the previous lesson, you know exactly what to do. Since the previous diagram might be a little bit confusing to some, I've taken the time to make a diagram in the format you all know and love.

The third LED, then connects it's short leg to the resistor which allows the electricity to flow without burning the LEDs which then connects to the Arduino's gnd. Being that the LEDs are directly connected to the Arduino which is hooked up to a battery, they all should light up! Now you have mastered the idea of using an arduino as a power source to directly give electricity to your circuit. Achievement unlocked! Next time on GearsnGenes' tutorial series, you will learn to manipulate your circuit, allowing it to do more than just be a constantly shining LED.

Enter the coding proccess! Until next time, pupils!Circuit diagram or schematic capture and PCB printed circuit board design is very essential to design electronics.

In this article, I am going to share with you top Arduino based projects which can be easily created by the beginners. These projects are carefully selected because these projects can be easily modified into advanced level projects.

The Water Flow Rate Sensor can be used in so many amazing projects.

Build Arduino Quadcopter with Complete Source Code and Circuit Diagram

There are things that we need to take care of while using the Water Flow Sensor. As per the datasheet, when water flows through the rotor, rotor rolls. Its speed changes with different rates of flow. If we can keep the pressure and flow constant we can make an accurate water volume measurement system.

I solved this problem by using a 12v Water Pump. I have also explained the complete circuit diagram, making, and Arduino programming. The MPU gyroscope sensor one of the most frequently used sensors throughout the world.

I believe every beginner should learn about the MPU Using the MPU sensor, you can build a self-balancing robot, a self-balancing bicycle, a hand gesture controlled robot, a self-balancing platform for a Camera, you can control an onscreen 3d model with this sensor, etc. The MPU sensor can be used in thousands of projects, but it is only possible if you know about the extreme basics, like its wiring with the Arduino and Arduino Programming.

You can build beginner and advanced level projects using this Real-Time Clock. You can make an Automatic School Bell, you can build a Sensor monitoring system which displays the sensor data with date and time information, you can make an automatic load management system using RTC DS, etc.

This tutorial explains the extreme basics, which will help you use this sensor in advanced level water quality monitoring systems. This is the era of 3D printing and CNC machines technologies. Sooner or later, every electronics hobbyist or professional wish to work on such fully automatic electro-mechanical projects. Before, you can make advanced level projects using the Stepper Motors you need to know about the Stepper Motors basics.

This tutorial explains how to use Stepper Motor. In this tutorial, a joystick is used to control the speed and direction of Stepper Motor. The LN motor driver can be used in so many projects.

In this tutorial, I have explained everything that you need to know about this amazing Motor Driver module. As a beginner, you should definitely learn how to use this Motor controller.

Things are becoming smarter day by day. Home appliances are controlled wirelessly using a cell phone App, the car engine and doors are controlled using a smart cell phone, the robots are controlled wirelessly, the sensors are monitored via cell phone, etc.Basic principal of ultrasonic distance measurement is based on ECHO.

When sound waves are transmitted in environment then they return back to the origin as ECHO after striking on any obstacle. So we have to only calculate its traveling time of both sounds means outgoing time and returning time to origin after striking on any obstacle.

And after some calculation we can get a result that is the distance. This concept is used in our water controller project where the water motor pump is automatically turned on when water level in the tank becomes low.

You can also check this simple water level indicator circuit for a simpler version of this project. Ultrasonic sensor HC-SR04 is used to measure distance in range of 2cmcm with accuracy of 3mm. The sensor module consists of ultrasonic transmitter, receiver and the control circuit. The ultrasonic sensor module works on the natural phenomenon of ECHO of sound. A pulse is sent for about 10us to trigger the module.

After which the module automatically sends 8 cycles of 40 KHz ultrasound signal and checks its echo. The signal after striking with an obstacle returns back and is captured by the receiver. Thus the distance of the obstacle from the sensor is simply calculated by the formula given as.

Here we have divided the product of speed and time by 2 because the time is the total time it took to reach the obstacle and return back.

Thus the time to reach obstacle is just half the total time taken.

Working of this project is very simple we have used Ultrasonic sensor module which sends the sound waves in the water tank and detects reflection of sound waves that is ECHO. Arduino reads the time between triggering and received ECHO. By using this methods we gets distance from sensor to water surface. After it we need to calculate water level. Now we need to calculate the total length of water tank. And we will get the water level distance. Now we can convert this water level in to the percent of water, and can display it on LCD.

The working of the complete water level indicator project is shown in below block diagram. A 16x2 LCD is connected with arduino in 4-bit mode.

In this circuit Ultrasonic sensor module is placed at the top of bucket water tank for demonstration. It means we are here showing empty place of distance or volume for water instead of water level. Because of this functionality we can use this system in any water tank. To program Arduino for water level controllerfirst we define all the pin that we are going to use in the project for interfacing external devices like relay, LCD, buzzer etc.

Now initialize the ultrasonic sensor module and read time of sending and receiving time of ultrasonic waves or sound by using pulseIn pin. After it we check conditions if water tank is full or water level is LOW, and take actions accordingly. I'm new with it. Tell me how to collect the code? Collect the code means? Check this article for Getting started with Arduino.

Can you tell me how to connect arduino to water pump using relay modul 4 channel? Hi sir, I have two tank and I like to monitor one tank with ultrasonic sensor with this circuitIs it possible? So take care to swap those supply if you want it to work and not smoke.

This support board is a suitable size for fitting to this robot and can be connected to two servomotors driving the robot by way of connectors that have been provided for this purpose.

The circuit shown here allows a mobile robot to detect information about its immediate surroundings by means of two microswitches end-of-travel detectorstwo photoresistors, and three infrared proximity detectors. All this will enable the microcontroller to steer the robot correctly by sending appropriate commands to the servomotors. The interface circuit for the three infrared detectors is standard and has already been used in [3].

Potentiometers P1, P2, and P3 let you adjust the current drive to the transmitting diodes, and hence the maximum distance at which the detector will be able to detect the presence of an obstacle. The 2. The microswitches make it possible to detect the presence of an obstacle on the route and thus avoid collisions. The two photoresistors make it possible to follow a reflective track, so the robot can follow a path marked out on the ground.

Then the pin is configured as an input, which puts it into high impedance. The capacitor charges via the photoresistor, so the pin goes from logic 1 to logic 0 after a time that is proportional to the time constant RC. Hence by measuring the time it takes the pin to go from 1 to 0, we can measure the value of the photoresistor, and thus the intensity of the light falling on it.

An additional expansion board that includes a quick prototyping area make it easier to connect the Arduino Nano support board with additional circuits electronic compass, real-time clock, maths co-processor, accelerometer used as an inclinometer, and so on.

This device can project attractive laser beam patterns on virtually any desired surface. The basic idea is to manipulate the path of a laser beam from a source such as a laser pointer.

The beam is deflected by a small mirror fitted to the end of a motor shaft. This cone strikes the second mirror on end of the shaft of a second motor. The beam from the second mirror goes to the projection surface. A wide variety of fascinating figures can be created by varying the speeds of the motors. All of this is controlled by an Arduino microcontroller, using a program written in C. The software can be downloaded free of charge from the web page for this article [1].

The speeds of the two motors are set by potentiometers P1 and P2 which are fitted with the red and blue knobs in the photowhose positions are read by the microcontroller. The microcontroller converts these two input signals into PWM outputs that determine the speeds of the motors.

The rest of the circuit diagram is simple. The two motors scavenged from printers operate at 24 V with current consumption well below mA. To be on the safe side, two channels of the ULN are wired in parallel for each motor. The laser diode is energized by the microcontroller immediately after start-up and is always on. The current is limited to approximately mA by a ohm resistor. To avoid problems with pulse noise from other supply rails, the Arduino is powered from a separate 6 V source, such as a rechargeable battery.

The author used the potentiometers to find various combinations of motor speeds that produce attractive figures.

They have been arranged in sequence to provide a show lasting several minutes, with a repeating series of fascinating figures in an automatic loop. This is included in the C code. This loop, as well as other pre-programmed figures, can be selected using a set of four switches. Your email address will not be published.
