pedalinio-18-footswitches-prototype.

I created this repository to share my experience of creating my prototype of the open source pedalino mini project. I am also sharing in this repository the files I created along the way. It was a great experience and journey. I think I spent the same amount I would have spent if I bought it in a store but !! I LEARNT A LOT :

• I discovered and learnt to use GitHub
• I discovered what happened in the last 25 years with microcontrollers. I used to program in assembler.. (incredible)
• I learnt somehow to use arduino and visual studio
• I learnt to design in FUSION 360 !! that software is free !! - PCBs and the entire project.
• I did PCBs again and instead of DIY at home, I learnt how to buy them in China. What a change !
• I did my first 3D print ever. I was wondering what 3D printing is really for. I discovered a new world.
• I discovered how cheap things are in AliExpress :) - no more amazon

Here are 3 pics of the end result:

My prototype

My prototype has the following features:

• USBMidi interphase that I wanted because my Bluetooth connection used to disconnect on my iPad.
• 18 footswitches leveraging 3 interphases out of the 6 available (6 footswtich ladder configuration)
• 3 external analog interphases leveraging the remaining 3 configuration.
• 18 2812b leds, one for each footswitch.
• LCD display.
• Externalized boot switch to select the profiles A/B/C. For this reason, I am using the 38pin DOIT ESP32 dev board instead of the 30-pins DEV board. (The boot button is in the GPIO-0)
• The mainboard PCB also has pins-out to connect the legacy-midi interphases (circuit to be built in another PCB)

Fusion 360

Please refer to the folder Fusion 360 to get the files and see how I designed the prototype. In this section I included some tips on how I thought the construction.

Creating the prototype

Please refer to the folder Fusion 360 export files for production to download the files to request the production of the different parts. In this section I also included some links to some of the components I used.

I hope this information is useful to you and do not hesitate to raise questions for clarification. I will try to answer as soon as I can. All the best, juani13973
