Some time ago i wrote a theory explaining how the touch sensors work, covering the resistance, the AC Hum and the capacitance touch sensors. Microchip has developed the mTouch(tm) sensing solutions. Part of the mTouch(tm) sensing solutions, is a series of PIC microcontrollers with embedded capacitance module. A list of these PICs can be found in this link.
In this article, i will use the PIC 16F1937, a powerful microcontroller with a 16-channel capacitance module. I will only use the 4 of them, but the idea to expand it to all 16 channels is the same.
