In daily life we analyze that some appliances are helping in human life to overcome the human efforts and struggles like water pump, washing machines refrigerator's etc. but we also concern with utilization of power as well. So we want to manage these things in a good and desire manners.
So here is a Arduino and real time clock RTC based adjustable timer for your appliance. You Just set you desire minutes to ON the appliance in each hour then save that. Than you will be feel easy.
This Circuit is especially design for water pump to suck the water from the ground after each hour.
Function buttons:
set: Press to enter in setting mode for timer ON and OFF minutes, Real time setting, Day setting then saving that values
++ : is use to increase values
-- : is use to decrease values
AOM : is empty right now for one more advancement I want to do (I will share in next version)
Components used:
- Arduino Uno
- RTC (DS1307)
- LCD 16x2
- Push button
- 7805 Regulators
- SPDT Relay 12v operated
- TIP147
- Optocoupler 817
- Resistors 10k, 220
- Pot-meter 5k for Contrast control with LCD
- 12v adopter 2A
- Li cell for RTC
