By using the QTouch ADC method, the analog pins of the microcontroller can be turned into capacitive sensor, without the need of any external circuitry.

Which AVR microcontroller to use?

ATMEGA 328P

  • very widely available, prize starting around 220 - 250 IDR (3$)
  • The smd chip has 8 ADC channels, but the DIL seems to only have 6 ADC channel on Port C, ADC0 - ADC5
  • prize, ca

Download ATMEGA328 datasheet

ATTINY 84

  • availability ok, prize starting around 150 IDR (2$), 1.50$ from Mouser
  • 8 ADC channels

What's the difference beetween attiny84A and attiny84 or Attiny84V (Low Power and expensive?) or Attiny841 (new edition of attiny84 or attiny84A)?

ATTINY 25/45/85

  • availability ok, prize starting around 100 IDR (2$)
  • only 4 ADC channels
