Basic MIDI controller  [schematic]

Postby DarkRain » 19 Aug 2015, 13:09

Hello guys, just a small project that i would like to share with you for whom is interested.
We are talking about a small MIDI controller that will send incremented or decremented PC-MIDI Messages (Program Change messages / 0 to 127) with the following features:
- UP / DOWN buttons
- for every send message a corespondent led will blink
- last send message will be stored in memory and it will be send when one of the buttons will be pressed for the first time after the power-up
Very handy for changing presets on a effect processor or any other device that accepts Program Change MIDI messages.
Arduino Pro Mini was used, the firmware was written in C and can be downloaded from here: https://dl.dropboxusercontent.com/u/152 ... END_PC.hex
Permission DENIED for using it in commercial products, for DIY purposes ONLY!
I will gladly answer any questions that you might have.

Best regards,
DeX

And it is not full list of arduino pro mini variations, that I find....

Most similar to the wiring diagram is Pro mini 328, second variant. But it is a problen to find it to purchase.
