Hello again everyone,
I just bought my first Arduino Uno board.
(no shields yet. Also, it's the one with the Atmel chip in the "cradle" (name??). Not the new one that has the Atmel chip soldered on (SMB?))
Anyway, I got a couple of other items, yet I'm at a loss as to how to connect all this.
I think I'm missing various components before making this work.
There are three main reference links I'm using:
High-Power Control: Arduino + N-Channel MOSFETUsing a transistor to control high current loads with an ArduinoHow do I connect a relay?As a review:
I don't need to control the speed of the DC motor... just give it 12v power.
Parts I have:
- Arduino Uno board
- TIP120 Darlington Transistor
- SPDT PC Relay (12VDC coil, Rated 10A at 120VAC/24VDC)
- Random assortment of 1/2 Watt resistors
My main questions are:
What diagram should I follow?
and
Power supply to the washer pump motor.
I can nail down the power supply to the Uno fine.
Yet, for the washer pump... ??
Today in Radio Shack (yes, I know) I saw a transformer.
I believe it was 120VAC --> 12VDC 3A.
Will this work?
I need to check the washer pump to see how much will the little motor draw (I'm not sure how many Amps).
Can I make it work with what I've got?
Thank you very much to everyone!!
