4. Usage
The module is mainly used to detect the infrared light. It outputs digital signal 0 and 1 through a
Comparator output. The output value will be 0 when infrared light is detected. And the sensitivity
is adjustable by the precision potentiometer.
Let's use it to control. When the output value is 0, the led will light up.
1. Connect the module to the D3 of Grove - Base Shield using the 4-pin grove cable.
2. Plug the Grove - Base Shield into Arduino.
3. Connect Arduino to PC by using a USB cable.
4. Copy and paste code below to a new Arduino sketch. Please click here if you do not know how
to upload.
