hello overpro, thanks for your work :D I followed everything, and the computer recognized the arduino as 2 game controller. I started to test with a button. I thought I just need to connect a collum and a row by a wire and the buttion should be on, I am right ? There no light on the game controller test One more question: Is that true that we must use the 1N4148 diode ? Thanks :)
