I am looking for some help on a circuit design for turning on and off some motor pumps from an arduino. My background is a programmer and I'm a bit weak on the mechanical side. I've been able to do this on a small scale, but the motors I will be using require more power than the little 1.5-3v ones I used for a concept. My main question is if a TIP120 would be able to handle the task or what should I use if I need to go with something else.
Here is the spec of the motor that I will be using. (2885 model)http://www.mabuchi-motor.co.jp/cgi-bin/catalog/j_catalog.cgi?CAT_ID=rs_360sh
I'm not sure if I'm reading this right, but they would be pulling 3-6amps?
I am looking to run them at 5v. There will be 6 motors total, but it would be rare to run at the same time, 2-3 at one time would be common. They would periodically run for short bursts anywhere from 1/8 second up to 3 seconds and strictly an on/off operation.
