Thread: GCode: open source paintball gun board/software

    looking forward to hearing about the updates. How much do the paintduino boards run?

    i think i am going to order a arduino nano and an oled and get to work on this. Going to be fun

    Get a Pro Micro instead. Its smaller and has native usb. This is also the same chip that the Paintduino uses. You'll need a FET to control a paintball solenoid as an arduino can only supply 40ma per pin. The Gcode sketch compiled fine and I was able to load it to my Pro Micro.

    on the schematic you have a second LED (LED2) that doesnt seem hooked up, is that necessary?

I swapped that connection this morning. Hopefully will be able to test it tonight.

    Also, I forget if I had mentioned it, but I replaced the 7805 with a more efficient, and much smaller, voltage regulator. It's now using one of these.
    would you mind please posting your updated schematic?

    i have this wired up completely on a breadboard. Huge thanks to sumorai for code and dirty engineer for endless patience and trouble shooting.

    The only issue i have, my eye logic is backwards somehow. Green = ball and red = no ball is correct, but it fires on red and no fire on green.

    Before i start delving into code, any ideas?

    I always consider that the eye logic should be "blocked = shot & clear = no shot". Also check the leads and make sure the wires are going to the appropriate places.

    Hard to troubleshoot a circuit without seeing it.

    working on cleaning up the breadboard as we speak
