Image of this project is below
Construction of Timer circuit using PIC microcontroller:
- Place step down transformer along diod base bridge rectifier convert 220V into 12V
- Place capacitor for filter circuit
- Place pig microcontroller and 7805 regulator for 5V power supply
- Interface microcontroller with shift resistor IC (4094) serial in parallel out
- 4 transistor (1015) used as a amplifier
- Common anode 4 digit display
Working of Timer circuit using PIC microcontroller
- When we push set button then set on time option is display
- Then we set the on time value by using up and down button’s
- Again push the set button then off time option is display
- Then we set the off time value by using up and down button’s
- Now press the set button again to set these value’s
- Now press down button to start the circuit. After press the down button timer is start and relay is on and On-time and off-time is displaying on digital display.
