This project is a beginner-friendly Arduino sketch designed to demonstrate how the Serial Monitor works in real-time. It calculates and displays the area of a circle using a simple mathematical ...

input PWM signal to counteract the natural exponential nature of the LED to make the LED look like it’s fading linearly. With trial and error, he found the most pleasing input curve to use can be ...

An Arduino Uno provides the processing power and drives the serial monitor. A joystick and a Hitachi H48C accelerometer are mounted on a breadboard and wired to the Uno.

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 ...
