Project Idea:
This project allows users to control the power delivered to an AC load by adjusting the firing angle of a TRIAC using a microcontroller. The power level is entered using a keypad, processed by an 8051 microcontroller, and displayed on an LCD. It’s ideal for learning microcontroller-based power control systems.
