ABOUT THIS PROJECT

1 / 9

Automatic watering system

A device that helps. Reduce labor time in people watering trees. Morning and evening Using the temperature calibrator to determine the function.

Step

Step 1

- In order to use it, we have assembled the circuit we need to work in each part of the device.

Step 2

- Once assembled, we will put the code into the A-rduino program.

Step 3

- When Run Code The command is as follows:

3.1 When the value of the gauge is greater than the set value Red light will appear.

3.2 When the value of the gauge exceeds the set

Code
