Less talking, more building!
In this installment we are going to assemble a Midi Input Circuit and connect it to your Arduino UNO. The Circuit itself is actually quite simple consisting of only a handful of parts.
In the last installment, we looked at a Circuit Analysis of a Midi Input and Output Circuit. If you are new to this series, I suggest you check it out. It will give you a better understanding of what you are actually building. Now, let's put this knowledge to use and start building the hardware.
I am assembling the circuit on a small solder-less breadboard. The video will walk you through the steps of putting it together. Take your time and double check your work. You'll be fine!
