I'm testing some ideas to see if a project is doable and successfully created a finger switch using some info on Google. However I accidentally didn't save the sketch and have painstakingly searched for the same script.
The idea is fairly simple. There are two open pins on a breadboard, and when my finger was placed over the top of them to connect them together the circuit was complete and it was able to control the state of another output pin.
If I recall correctly the set up was. Digital Output Pin to first open pin, second open pin to 220 resistor to ground and 5v. I think. However it worked perfectly, when I put my finger on the open pins an led came on. Can anyone help me recreate this.
