Hello !

Today I will show you how to make a capacitive sensor with Arduino UNO.

Step 1: Watch the Video !!!

Step 2: Parts for the Project

You will need:

  • 1 x Arduino board
  • 1 x 1M resistor
  • 1 x Touch plate
  • 1x Breadboard
  • 1 x LED
  • 2 x Jumpers

Step 3: Put All Together

First plug in the resistor in pin 4 and pin 8 of the Arduino, then connect the touch plate with pin 8 of the Arduino.

Now plug in the LED to the breadboard, connect LED's "-" to Arduino's GND and "+" to pin 7.


Step 4: Upload the Sketch

Connect your Arduino to a computer and upload the sketch which you can get from here.

You will also need this library.

Step 5: Done !

You are done, touch the plate and the LED shoud light up. You can modify the sketch and for other "capacitive" needs.
