Features
1. ANALOG SENSOR: The grayscale sensor is an analog sensor, used in conjunction with the sensor expansion board v5.0, can perceive different colors and generate corresponding signals.
2. GRAY VALUE TEST: Including a white high brightness LED and a photoresistor, according to the strength of the light, to achieve the gray value test.
3. 3 PIN DESIGN: With 3 pins, which are power positive VCC, power ground GND, signal terminal OUT, which can be directly connected to the analog interface of the controller.
4. MULTIPLE USAGES: Can realize interactive works related to color, and can also be used as a line following sensor or a football robot field gray recognition.
5. EXAMPLE PROGRAM: Connect the grayscale sensor to the controller according to the program, and observe the value output by the serial port under different grayscale values.
