Making a PCB UV Expose Timer Using PIC16F876A With MPLABX XC8
In this design, I use the following stuffs to make a timer work well for my personal use:
- A variable resistor used for adjust time
- An ENTER button used for inputting the time value
- A LOAD button used for reading the saved timing from previous setting
- An 8-digit multiplexed displays for display the time
- An output relay driver to switch the lamp on and off
- A buzzer alert the beginning and the end of the running timer
