I was just wondering if it's possible to drive multiple transistors using one Arduino pin. Here's an example of my current setup: [image] You can see, I'm using the transistors to make/break the connections between the Arduino and the ZIF socket. Ideally I'd love to just use one pin to switch any…

Multiple transistors from one pin?

No problem. Just pick your transistor base resistors so that no more than 40mA comes out of the Arduino pin.
