Hello, I built this game http://benryves.com/products/avrtvgame, and i want to replace pushbuttons with this remote control http://danyk.cz/avr_do3.html. I now the working principle of transistor switch, but i think, that there cannot be used. Can anyone tell me, how could o connect it? I mean some circuit, which will act like a pushbutton, when no voltage will be at the input, the pin of Atmega will not be connected anywhere, but as soon as the logic level voltage (from the output of the Attiny) will be at the input, it will connect the Atmega pin to the ground. Thank you for your answers!
