In the previous video (https://youtu.be/LtavRdUBJ7E), you learn to connect Soil Moisture Sensor to Arduino. You can make Automatic Watering System for plants using Arduino. In this video, we are going to extend our previous experiment by connecting a relay and water motor. Write a program to take input from soil moisture sensor and switch on or switch off the water motor based on the data received from soil moisture sensor. Let’s look at the required components:
Arduino Uno R3: http://amzn.to/2srIMT3 | https://goo.gl/MkGoQC
Soil moisture sensor: http://amzn.to/2sQLiCJ | https://goo.gl/B9ewV6
