Circuit Setup

1. Connect the light spectrum sensor’s VCC and GND pins to the 5V and GND on the Arduino.
2. Connect the sensor's output pin to an analog input pin (e.g., A0) on the Arduino.

The sensor detects the light spectrum and sends the data to the Arduino for processing.

Code for Light Spectrum Analysis

Upload the following code to your Arduino to analyze the light spectrum:

const int spectrumPin = A0;

void setup() {
  Serial.begin(9600);
}

void loop() {
  int spectrumValue = analogRead(spectrumPin);
  Serial.print("Light Spectrum Intensity: ");
  Serial.println(spectrumValue);
  delay(1000);
}
            

Explanation

The sensor measures the intensity of light at different wavelengths, and the Arduino processes the data to analyze the light spectrum.

Troubleshooting

• Ensure the sensor is properly connected and placed in an area where light is present.
• If the readings are incorrect, check for calibration issues or faulty wiring.
