Hi there everybody!
I would like to build something similar to the "makey makey"
but instead of controlling a computer, i simply want to control
8 other pins on the atmega32. As i understand i have to put a large pull-up
Resistor on the input where the marshmellow would go and then ground
whoever is touching the marshmellow. But where i get lost is when i
have to program a filter to remove the noise from the input. I believe it
should be a "moving average"-filter but i have no idea how to implement it?
I do have experience in programming and in electronics, but not in DSP,
just to give you a hint of how complex the answer can be
