How to Implement Scrolling Display for MIDI Inputs on Arduino Opta with SSD1306 OLED?
https://www.youtube.com/shorts/tMQWNb_yzHs Project continues to progress. Works well in manual mode as seen here, but I also have an automatic mode that goes through a drum pattern.
What got me stuck (and it still is not perfect, as it's using a blocking/delay() function in auto mode) is that if the solenoid isn't triggered for long enough it won't fully extend all of the time.
I bumped it up to 50 milliseconds per a previous project, and also added a 2200uF capacitor between the + and - supply and now it seems to work well.
So I guess the lesson is that solenoids aren't instantaneous... As obvious as that might be now, ha.
