Hi I purchased this Vacuum: https://www.sparkfun.com/products/10398I also picked up this mosfet: https://www.sparkfun.com/products/12959I have an Arduino MEGA and I was wondering if I could power this vacuum using a 12v 4.5Ah battery.Also if I were to be able to use this battery with the Mosfet to power the vacuum on and off how would I wire it. Thanks.
Sorry for not specifying. Yes, I simply want the Arduino to be able to turn the vacuum on and off. The reason I am not using a switch is that I have preexisting code that I want to activate the vacuum.
It says under Documents that pump is 12W, so at 12V that's 1A, more at startup if that's the "running" power. I don't know how to get the stall or startup current, given the running current, but it's probably about 5A or so for a short while. (Don't quote me.)So you need to check if your battery can provide that current; the Ah you quote is capacity, not the current it can supply.In principle you would hook it up like this:
I confess to not opening the mosfet link until after my post with the pic, and didnt realise it was a breakout with pull down, I just saw the word "mosfet". Digrams correct at the component level of course.
Wow: a dollar for the actual mosfet and 4x that for the board....
Um ... Didn't the board already supply a Gate grounding resistor?
Also, anyone got any idea what is the gate-source diode doing in RFP30N06LE?
What board is that?
I also picked up this mosfet: https://www.sparkfun.com/products/12959
Any idea on what's going on with the MOSFET's GS Diode?
The body diode you mean, between drain and source?
