# MIDIPedalBox
## Trinket M0 + CircuitPython USB MIDI Pedal Box
## Wiring
The wiring is pretty straight-forward. A single wire goes from each button to pins 1,2,3,4 and a common ground connecting everybody.
## Parts
The parts used for MIDIPedalBox:
- 1 - Adafruit Trinket M0
- [Buy from Adafruit](https://www.adafruit.com/product/3500)
- A [QT Py](https://www.adafruit.com/product/4600) or [Seeed XIAO](http://amzn.com/B08745JBRP?tag=todbotblog-20) will work too, with minor code modifications
- 4 - effects pedal switches
- I chose these [generic momentary ones](http://amzn.com/B076V8C3LV?tag=todbotblog-20),
but there are many to choose from and most all will work. Be sure to check dimensions to be sure!
or if you want push buttons instead of foot switches,
- 4 - 12 mm momentary buttons
- I used [these from All Electronics](https://www.allelectronics.com/item/pb-138/spst-n.o.-pushbutton-red/1.html), but the equivalent are [available from Amazon](http://amzn.com/B07F24Y1TB?tag=todbotblog-20)
If you want to add serial MIDI out, the CAD includes a hole for a panel mount MIDI jack,
like [this one](http://amzn.com/B01GBT9RC0?tag=todbotblog-20)
