AC Power Controller with LCD & Keypad Interface
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.
 
Components:
  • 8051 Microcontroller
  • Matrix Keypad
  • 16x2 LCD Display
  • TRIAC
  • Crystal Oscillator
  • Resistors, Capacitors, Diodes
  • Transistors
  • Transformer/Adapter
  • Cables & Connectors
  • PCB & Breadboard
  • Push Buttons, Switch
  • IC & IC Sockets
  • LED
  • Lamp 
 
Software:
  • Keil µVision IDE
  • Embedded C (for 8051 programming)
 
Project Features:
  • Real-time AC power control
  • Keypad input for power percentage (0–100%)
  • LCD display for live feedback
  • TRIAC-based phase angle control
