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
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 should light up. You can modify the sketch and for other "capacitive" needs.
