Arduino already include on-chip PWM controllers, making this effectuation easy. In short, PWM is a way of digitally encoding analog signal levels. MyDuino! Looking for a solution to build this circuit ...

I made this Arduino 8 bit binary led counter as a solution for one member from Arduino forum. He asked if somebody can make a project that displays a decimal number in 8 bit binary format using 8 leds ...

I use that in a lot of Circuit VR posts so you can click on a circuit and see it live. However, the simulator does not save the source code in the virtual Arduino. You have to do that yourself.
