Hi, I have an external filler which has a 3 pin din plug connected to a foot switch. I want to control the filler via the arduino. The 3 pins are as follows :
pin 1: Input or "Trigger" +5v - 50vdc pin 2: Output +24 vdc max 250 ma pin 3: ground
I am assuming pressing the foot switch just connects pin 1 to pin 2 temporarily.
What type of transistors or relays would I use to implement this "automated foot switch" ?
thanks for all your help, -tom
