PIC Industrial and Domestic Timer (Relay Controller)

Project is titled "Industrial and Domestic Timer" is a time controller or a Time controlled relay project in simple words. Though it seems simple to say but the features of this project adds a great learning curve in both hardware and software part.

This project is buit around Microchip PIC Microcontroller PIC16F877A. Hardware includes DS1307 for time keeping, 16x2 LCD for display, 5 Push buttons and 8 relays. The alarm settings are stored in internal EEPROM of PIC microcontroller. The code for this project is written in C for Hi-Tech C Compiler.

   


Some Highlighting features are:
  • 32 alarm settings for 8 relays including on off but the number of alarms can easily be increased upto 46.
  • 16x2 LCD and 5 push buttons for user interface.
  • Microchip PIC16F877A as controller and DS1307 to manage time.
  • PIC16F877A’s internal eeprom to store alarm settings.
  • PIC’s code is written in Hi-Tech PIC C compiler.
