What you need

• Arduino or compatible microcontroller
• Connection cable
• 10kΩ resistor
• Optional protection short

Steps

1. 1. Connect the sensor to the microcontroller using VCC and GND.
2. 2. Connect the resistor between VCC and the sensor input pin.
3. 3. Connect the sensor output pin to the microcontroller’s analog pin.
4. 4. Add a protection short between VCC and GND if necessary.
5. 5. Load the following code onto the microcontroller.
6. 6. Check the light values read by the sensor.
7. 7. Adapt the code for your project.
8. 8. Test the project.

Example code

```void loop() {  int sensorValue = analogRead(A0);  Serial.println(sensorValue);}```

Mini project

Create an illumination system that turns on/off based on ambient light every 30 minutes.

Common mistakes

• Forget to connect VCC and GND.
• Do not use the pull-up/pull-down resistor.
• Connect the sensor output pin to a digital pin instead of an analog pin.
• Omit electrical protection.
