I'm trying to run an Aerobed motor for a short period of time to "make it snow" by blowing a bunch of hole punch snowflakes for a Christmas decoration. The blower motor is one of those DC car cigarette lighter type that run on 12V DC. I understand the coding portion of this, that part is pretty clear from the code sample. I'm using the Basic Stamp, Board of Education revC.
My question is on wiring up the single relay board. I've never used this component before, or any relay for that matter, and the documentation is a little unclear (https://www.parallax.com/downloads/single-relay-board-product-guide
). I'm not sure if the 5V is supposed to come from plugging it into Vdd, Vin, Vss or a separate 5V battery pack altogether. The same question applies to the ground wire, where does that go?
Also, I know I need to put a fuse in the load side based on the documentation, but any advice on what type of fuse I should get? Is that just a fuse for a car, would that suffice?
Here is the product page:
Any help would be much appreciated! Thank you!
