Do you know what a Peripheral Touch Controller is on AVR devices? Have you ever wondered how capacitive touch sensing works? Do you have a capacitve touch screen in your next project? Does your next project need a capacitive touch button, a slider button, or a wheel touch sensor? This introduction video for AVR’s Peripheral Touch Controller, or PTC, gives an overview of capacitive touch sensing using the PTC as the example module. Learn the different benefits of self capacitance and mutual capacitance buttons and when to use each type. AVR’s PTC supports both binary buttons, or buttons that turn On and Off, as well as Interpolated sensors like touch sliders and touch wheels.
