Abstract:
In this project we are going to operate a machine or liquid pumps for a small duration. This project provides the facility of automatic switch off after the required time duration. By using RTC DS1307
We will start the clock.
16 X 2 Liquid Crystal display (LCD) is connected to the microcontroller to display the status of the liquid pump.
This project uses regulated 5V, 500mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac out put of secondary of 230/12V step down transformer.
