Explanation Overview: My final project is an 8-Step, 4-Channel Drum Sequencer that incorporates NeoPixels, and a potentiometer that sends CC messages to a DAW. In the video below, I chose to use Ableton to demo my project. There are three major components to this code which I will break down in the sections below. DrumContinue reading “Digital Electronics Final Project (!!!)”

Push-On Push-Off Button Explanation: The push-on push-off button concept has three major parts: checkButton(); flipButtonState();, and updateLed();. The checkButton(); function is very similar to the code we’ve used in the past for MIDI notes. First, we set lastButton1State equal to button1State, and button1State equal to the status of the buttonPin (pushed or un-pushed). From there,Continue reading “Digital Electronics Lab #7”
