Each of the 14 digital pins on the Arduino Uno can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions. They operate at 5 volts. Each pin can provide or receive ...

Note: Some pins are not connected on a standard Arduino Uno R3 but still listed so you can use them if you had a custom board. It might also be possible that your ICSP header of the 16u2 is flipped ...

Servo motor works on the principal of Pulse Width Modulation (PWM) and its angle of rotation is controlled by the duration of the pulse applied to its control pin. Here in this tutorial we will ...

I myself own an Arduino Uno R3 and found that it can simplify my projects development and microcontroller programming, but sometimes I need to know the Arduino pinout. That is why I have written this ...

The purpose of this project is to provide a 4-20 mA output from a PWM signal generated by a microcontroller. One of the more interesting applications of this circuit would be to replace or to realize ...
