I just bought this solenoid (seeedstudio.com/wiki/DC_fram … id_VL-0063) and was going to hook it up to an Arduino Uno (later some smaller Arduino) and wanted to verify a few things…
First, since this says 14.8V that means I’ll need to power it through a transistor from the Arduino, right? What about the P2N2222AG included in the ARDX kit? I think that has a high enough V to support it.
Second, does that mean I should join two 9V batteries in series to drive the solenoid? Or is that too much (18V)? Should I get a battery that is more specific?
Finally, I’ll include a diode as well since it has a kickback when the solenoid is turned off. Does the one included in the ARDX kit work for that (1N4001)? How would I figure out that it did?
