Grayscale Sensor

Back to article list

Usage

AOUT is the IR sensor analog output, the voltage follows IR LED reflection intensity. DOUT only has 0 or 1 state, the changing spot defined by onboard screw. Turn the screw clockwise to bring the gate close to VCC, and turn it counterclockwise to close to GND.

Sample Code

Hardware Connection: Connect the Gray Scale sensor to the Analog1 port of the MATRIX Mini R4.

Result: The Grayscale Sensor value will be shown on the OLED from 0 to 1023. The return value of black is larger and the return value of white is smaller.
