Breadboard capacitive touch sensor tutorial

Build your own capacitive touch sensor on a breadboard! In this tutorial we will use the PIC16F627A microcontroller to build a simple capacitive touch sensor from scratch. And to keep things interesting, we will build a momentary switch, a toggle switch, a timer, and a 3-level dimmer. Thanks for watching, and let me know in the comments if you have any questions!
