Because I bought a MOSFET to try just that, but I accidentally bought a power MOSFET that requires 10v to activate the gate, and the Arduino only puts out 5v max. I also bought some relays to try, but I accidentally bought NC instead of NO. I still have a lot to learn about using the Mouser search engine, and reading the data sheet of ICs before I buy them.Originally Posted by everlastsupport
Sure, but since these are all unused pins, I think that doesn't really matter.If you take them all to ground via one R any one pin going high will pull them all.
