Tutorial: How to Use Capacitive Touch Dimmer

The Capacitive Touch Dimmer allows you to control the brightness level of an LED through a touch-sensitive interface. Useful for home or industrial lighting projects.

What you need

• Arduino
• LED
• 10kΩ Resistor
• Power Cable

Steps

1. 1. Download the example code from the specific GitHub repository.
2. 2. Connect the Dimmer to pin A0 of Arduino.
3. 3. Connect the LED to digital pin 9 and VCC with a 10kΩ resistor between GND and the Ground pin of the Dimmer.
4. 4. Connect the VCC of the Dimmer to the VCC of Arduino and GND to GND.
5. 5. Upload the code to your Arduino.
6. 6. Experiment with touch on the Dimmer to control the brightness level of the LED.
7. 7. Adapt the code to customize the behavior of the Dimmer.
8. 8. Check the datasheet for further details.

Example code

```void setup() {} void loop() { int value = analogRead(A0); analogWrite(9, value); }```

Mini project

Create a lighting system with a single button to turn the lighting on/off and a dimmer to adjust the brightness.

Common mistakes

• Do not connect the Dimmer directly to VCC without a resistor.
• Set the correct read pin in the code.
• Verify the proper power supply of the Dimmer.
• Ensure that the code is correctly uploaded to the Arduino.

Recommended accessories

• Arduino UNO
• LED
• 10kΩ Resistor
• Power cable
