smart board projector bulb
smart board projector bulb.This article will give a brief overview of the capacitive touch sensing technology and the basic principles of its implementation. This article will show how to use CVD (capacitor divider) technology and a microcontroller peripheral called Charge Time Measurement Unit (CTMU) to achieve a low-cost capacitive touch-sensing design with minimal external components. The reference design shows how to replace the mechanical switch with a capacitive touch-sensitive button.
