Example Code for Arduino | Analog Grayscale Reading of Smart Grayscale Detection Sensor

In analog mode, the brighter the Sensor detects, the brighter LED will be. You can connect the sensor to analog pin to read the Grayscale from the sensor, just as the normal grayscale sensor.

Other Preparation Work

Just short click the button and the mode will be changed between analog and digital.

Sample Code

int grayscalePin=0;
void setup()
{
 Serial.begin(9600);
 Serial.println("Smart Grayscale sensor:");
}
void loop()
{
  Serial.print("Grayscale:");
  Serial.println(analogRead(grayscalePin));
  delay(500);
}

Result

The brighter the Sensor detects, the brighter LED will be. The serial monitor outputs the grayscale value read from the analog pin.
