Thanks to everyone who has helped me so far. Without going into tons of detail, you could say that a function on the target device is currently "latching" (press on, press again off) and I need it to be momentary. That's the root of the problem, and the impetus for this project.
Q5. No feedback from the target device. And yes, the desired function is as follows: While the pedal is pressed, target device is "on," and when the pedal is released, target device is "off."
Q6. No fail-safe requirement, this isn't mission-critical, medical, life safety, or high-speed machinery that would pose risk of injury. However, it might be prudent to add some kind of "reset" button to restore the system to its default state. Depending on the implementation, perhaps it would reset automatically if you cycle the power.
Thanks again and please keep your ideas coming!!
