@lostless the number of pulses are just to tell the microcontroller (or computer) which coins you are putting in. So you can set a quarter for 5 and a dime for 4 and so on. So when you set up an electrical piggy bank. The computer can tell which coins you put in. I'm guessing I would have to put some type of resisiter for this to work which is beyond my present capabilities. I went ahead and bought one off of X Arcades site. They have one with the microcontroller and stuff hooked up so all you have to do is Jerry rig it to your buttons or just connect it straight to the USB encoder. So hope it all works when it comes in lol
