make AUTOMATIC WATER DISPENSER || ARDUINO project || part-2 || Code and Circuit explanation.

Hello guys. My previous video was on how to make an automatic water dispenser using arduino uno and some sensors and other components.
In this video i will explain the code and circuit diagram of automatic water level sensor. circuit diagram is also shown in this video. To understand this video, you should have some knowledge about relay.
link for code: https://drive.google.com/file/d/19NvE...

parts are:
1. arduino uno
2. water level sensor
3. 5V, 1channel relay
4. 9.6V battery ( to power motor)
5. 9V battery (to power arduino)
6. simple DC motor (for water pump)
7. 2 resisters (220 ohm, 10k ohm)
8. 2 LED's (red , green)
