Step 1: Gather All the Necessary Parts
2. 10mF capacitor
5. breadboard or perfboard (if you choose to perf, you will obviously need a soldering iron and some solder)
Step 2: Build Your Circuit
pin 1: Power (3.3-5V)
pin 2: Output (in this case I used a red LED)
pin 3: Ground
pin 4: Power
pin 5: Power
pin 6-7: 10 micro Farad capacitor. These pins also connect to the input wire.
pin 8: Ground
Step 3: Input Wire
You can see how the light turns on and off when my finger touches the wire.
Step 4: Connect to a Microcontroller
In this example, I used the NET connect software to create a flash animation that changes its shape according to a user's touch.
