After making a successful prototype of my MIDI controller, I decided to start planning the final product that I want to make. The controller that I had in mind has multiple different types of inputs, for different applications, including: dials, buttons and sliders. Before buying all the components that are needed, I put together a rough diagram of the controller. This is to get an idea of how the controller is going to look, but also, to make it clear to myself how to wire it together.
The major difference in the final controller to my prototype is that I’m using an Arduino Mega rather than Uno. This is allows me to expand the controller with different input types and amounts if needed, as the Mega has an increased amount of analog and digital ports. The other major difference is that I’m not using a breadboard, unlike the prototype. This means that all the wires and components will have to be soldered together.
I put together a list of all the parts that I need to get for the MIDI controller, including a price list, allowing me to make a budget for the controller.
