It is ambient light sensor test on the OpenCR board.

Pinouts

Green : Signal

Red : Vcc

Black : Gnd

Specification

ambient light sensor specification

Supply Voltage : 3.3V to 5V

Illumination range : 1 Lux to 6000 Lux

Interface : Analog

7. 7. 1. 1. Code

LED turns off/on sequentially depending on the light received by the sensor.

LED turns off in bright place. If it is dark place, the LED turns on.

This sensor is an analog sensor, connect it to port A0.

It is a code that turns on/off the LED depending on the brightness of light changes.
