Basic USB Midi Footswitch. ### Parts * 1x Atmega32U4 Based Arduino or Clone (mini form factor) * I used https://www.amazon.com/gp/product/B01MTU9GOB * 1x 10k ohm resistor * Some Wire * 1x 6mm Button * I used https://www.amazon.com/microtivity-IM206-6x6x6mm-Tact-Switch/dp/B004RXKWI6 * 1x soft mount standoff (optional but makes the whole thing more solid) * I used https://www.amazon.com/NIDICI-Anti-Vibration-Mounting-Standoffs-Controller/dp/B071WBZC9K/ref=sr_1_1?crid=3BZ2VTU7F63UV * 2x M3 Screws * I used https://www.amazon.com/iExcell-Internal-Drives-Button-Socket/dp/B0716Y5WZZ ### Tools * Wire Strippers * Hex Driver * Super Glue * Hole Punch (Used for expanding screw holes and punching holes for button, you can probably use something else) * https://www.amazon.com/gp/product/B073WY2HR1 ### Assembly * Punch button holes in case top * Expand screw holes to grip M3 Screws * Attach wire leads to button feet * Run button leads through case top * Wire the Arduino the way they do in the simple button example * https://www.arduino.cc/en/tutorial/button * [Optional] Glue Ardunio in case * Close the case lid and screw the front of the lid in with soft mount standoff or M3 Screw * Screw in switch plate * Test Button action, if you press and the button stays down, file a bit off of the nub on the switch plate. When the switch plate can depress the button and release easily it is at the correct height. * If using rubber standoff, screw m3 screw through the front of the switch plate and into the rubber standoff * Flash arduino with provided code, right now it just outputs middle C, you can modify it to output whatever you want.
