Hi all. I want to modify an effect pedal with my arduino. I have managed to do all what I wanted excepted something with one of the toggle switches. This one has a strange behaviour and I can't do what I want with it so I come to you to see if someone can help me. Here is the problem, this is a spdt switch an led is connected to it, when I start my pedal, whatever the switch position is, the led is off, which means that wether the position is HIGH or LOW, the controlelr inside the pedal is LOW at start. So, does anyone know a way to do the same with arduino and that would be having the switch LOW when it starts even if it's HIGH? In a way, what I want to do is to convert the toggle switch into a momentary switch... Any help is welcommed. :.
