Automatic Plant Watering System Circuit Diagram

The below circuit diagram uses Arduino UNO R4 WiFi as a main controller, but you can use any other microcontroller by swapping it and making little modifications to the code. Here I decided to use Arduino UNO R4 because it has an in-built LED matrix for mimicking plant facial expressions.

We must ensure the components are connected correctly as per the above circuit diagram. Note that we can’t directly drive the water pump from the Arduino UNO R4 Wi-Fi peripheral pins. For that, we need either a motor driver module or a relay module. For simplicity, I opt for a relay module with an external power source.
