Controlling Water Pumps and Solenoids With Your Arduino

This video is a quick tutorial on how to control devices live solenoids and water pumps from your Arduino using a relay. Once you've got the basics down

Hahaha he looks like Manny from Modern Family. But thanks great video.

thanks man, just got my first adruino last night, did the first couple tutorials. Can I ask where you got the water pump from?

[theoremsnagesh]

Can you please post a wiring diagram? in video its not clear....

Recently I bought one of those mini 9v water pumps you can get off of eBay for $2.99. I hooked it up to a momentary switch and a 9v battery, and it works just how I want. However when I touched the 9v battery, it was extremely hot! What did I do wrong?

Where is this online store of yours you're talking about? LOL. Would love to know

Good day, can I use the relay + 5 volt signal (from Arduino or Ethernet SmoothStepper) to control a 110 volt pneumatic solenoid valve ? Thank you

Robot Geek  What about flow/speed control? Would you use PWM and a fast switching transistor?

[lauradahlstrom]

Agreed. Where is your online store? Also where did you get your pump?

Is it possible to use one 5v 2-channel relay or one 5V 4-channel relay to control TWO 110VAC solenoids at the same time?

[NigelLoller]

What about motor/solenoid resistors and capacitors re emf?

[MastaAce]

Under which section in your shop can I find the relay?

[rodrigopombo]

can you give me the schematics to the electical mechanic rellay (srr for the english btw)

[atm]

Is it necessary to connect a diode on the relay?
