27ace27 Posted May 27, 2009 Share Posted May 27, 2009 is the joystick designed so that when the buttons are pushed, a ground signal is sent to the appropriate pin? this is my theory, but I need confirmation for my project. In the schematic, what I thought was when the buttons were pushed, the positive signal went to ground. so I put in the diodes to prevent other buttons from activating multiple LED's. but if this was the architecture, there would be no practical way that I can think of to read the pins, and if the first design described is the one used (which I am betting on) this schematic would block out the signals making the joystick useless. The only fix I can think of (correct me if I'm wrong) is to remove the diodes, change the transistors from NPN to PNP, and place them on the opposite side of the switch.LED__s_vX.bmp Quote Link to comment Share on other sites More sharing options...
