LOLShield MIDI Lighting Effects

This project goes back to the LOLShield and uses it to trigger some LED animations in response to MIDI events. https://www.youtube.com/watch?v=Hu4hc7NGaGI&feature=youtu.be Warning! I strongly recommend using an old or second hand keyboard for your MIDI experiments. I am not responsible for any damage to expensive instruments! These are the key Arduino tutorials for the main concepts … Continue reading LOLShield MIDI Lighting Effects →

Arduino R2R Digital Audio – Part 3

So this is where we start to get closer to some proper direct digital synthesis using the hardware developed in part 1 and moving on from the timer-driven code developed in part 2. In Arduino MIDI R2R Digital Audio I add MIDI. In Arduino PWM Sound Output I talk more about the theory of PWM. https://youtu.be/1MPNHMQ-2vs The … Continue reading Arduino R2R Digital Audio – Part 3 →
