Arduino & RGB Common Cathode LED Rainbow using ATmega328P with Proteus Simulation
Introduction This microcontroller project demonstrates how to create smooth RGB color transitions using an Arduino-compatible ATmega328P and a common cathode RGB LED.By leveraging PWM (Pulse Width Modulation), the project generates a continuous rainbow-style lighting effect that cycles through multiple color combinations.It’s a great example of how embedded systems handle LED brightness control in practical electronics.The […]
