How to use a Contactor with an Arduino

[@gordonfrank]

Excellent demo of how to use a contactor with a lower amperage relay. The Arduino part was a bonus.

[@DuctTapeMechanic]

Thank you!

[@emoryolsoff96]

Hey DuctTape Mechanic - if I wanted to supply the smaller relay with power using a usbc on the main board, is that possible? Instead of using the stepdown transformer. Thank you.

You could try using a contactor with a 120 volt coil. You can use the relay to switch a very small amount of 120VAC, that powers the contactor with a much bigger load. Does away with the need for the 24VAC transformer. Amazon has contactors with all sorts of coil voltages - I've even used a contactor with a 240v coil to control a 25000 btu Window air conditioner using one of those cheap Sonoff smart switches. Still an excellent video, btw.

That is useful information. Doing away with the transformer is great. Thanks for watching!

I got to ask were ya learn all the stuff u know about from school? I no it's a crazy question but I am wondering?

[@DuctTapeMechanic]

I have always had a passion for electronics so a lot of it has be self study. I enjoy it!

My washer started out great did everything Wars done everything until the final Spin and not skin still haven't figured it out yet.? Any help or answer would be great .

[@DuctTapeMechanic]

@@akamomakawife4928 is there any grinding noise? Also what model is your washer? It could be the shifter is broken if everything else works good but it won't spin. Hope this helps

Really nice man

[@usmanriaz8396]

what about flyback diode ? won't relay coil produce back emf ?

[@DuctTapeMechanic]

It's an AC relay so probably not a good idea to use flyback diode.

Cool! next time you should try to show us the wiring diagram, so we can try it! Thanks man

[@DuctTapeMechanic]

Thanks for the feedback! I will try to add a wiring diagram next time.

[@ClintChance]

I mean I think with how spread out he made this the wiring diagram would be quite simple to infir

[@cinderblue3251]

You would get more views and it would help others out. Next level

9 amps at 220 1980W. The light takes probably 2/3 of the power.

[@Reprogram4595]

its 120v not 240

[@MuhammadYamman]

Nice!

[@mithunxavior]

Ssr vs contactor

[@farahnasir5023]

Cool!

[@abidyasin3697]

[@pauleohl]

The interesting part is the Arduino and you assumed that we know what it does and how to utilize it.

[@haseebsamadi]

Arduino is pretty easy to learn, KZbin is full of tutorials
