In the original demonstration, I used a white noise generator to show the effect going on and off, but in vivo, the bypass didn’t work. Turns out the actual bypass wiring was incorrect and the affected white noise—the effect “on”—was most likely interference from the bypass being activated. The original idea was to replace the 555 timer in the Incandenza Bypass with an Arduino, but in practice, the bypass didn’t function properly. I had to rewire it, ultimately wiring the DPDT relay like a conventional DPDT foot switch.
Other changes I made included switching to an Arduino Nano for better space management. I also reassigned the LED control: instead of being triggered by D2, the LED is now tied to the relay. However, users can easily move it back to D2 if they want to incorporate specialty LED lighting. The LED-related code remains in the original sketch for that reason.
