By controlling analog circuits digitally, system costs and power consumption can be drastically reduced. Arduino already include on-chip PWM controllers, making this effectuation easy. In short, PWM ...

Here is a simple, yet useful circuit of an Arduino 4-digit 7-segment LED display unit. The module used here is a self-contained, compact common-cathode module containing four 7-segment LED numeric ...

This project takes the classic game of Connect Four and turns it into a game played with a small joystick. An Arduino Pro Mini and generic microcontroller act as the brains with a matrix of LEDs ...
