1)Arduino Uno What it is: A small computer board that we program to control everything. How we use it: It reads data from the moisture sensor and decides when to turn on the water pump. 2)Soil ...

The soil moisture sensor module , built around the LM393 comparator, gives an active-low (L) level output when the soil is dry (determined by a pre-setted threshold value). This digital output (wet ...

void pinMode(int pin, int mode) Tells the Arduino whether the digital pin is an input or output. mode can be either INPUT or OUTPUT. int digitalRead(int pin) Reads the value from the digital pin. The ...
