Capacitive sense buttons and pads are awesome, but many of the available systems are either propitiatory or require a dedicated IC. Toumas decided to code his own based on a closed source Atmel example where a single ADC pin is used for capacitive sensing. He reverse engineered it, and documented...Tags: AVR, capacitive sensing, touch

We think DIY capacitive touch sensing buttons, and sliders are cool. Designing and shaping your capacitive panels can be a pain. Here is an app note by Microchip that covers all the basics required to get your capacitive touch sensing project started. This app note starts with which pad shape...Tags: app note, capacitive sensing, PCB layout
