Seriously every time I want to update my arduino skills I find that the bloke that seems to have something of an Indian dialect always delivers in a fast decisive manner and it's always clearly layed out with no fluff. You Sir are a Gentleman and a scholar. Another success. Thank you so much brother. Greatly appreciated. Subbed!

[kusnezoff]

as soon as you started to talk I just knew you were Canadian. clear and to the point. no wasted talking.

I couldn’t figure out why mine wasn’t working and now that you explained it I’m super happy, I liked your video!!

[flintread]

Thank you, I used this exact method to upgrade my laser cutter to automatically activate my air assist pump during a cut when activated in the cutting software so much cheaper to build a relay control box than spend £260 on a kit for the same thing!

Great video explaining the Songle relays. I just included them to control my train turnouts and isolation (power) tracks using an Arduino. Since the turnouts only need about 150ms of power to trigger the solenoid, these are perfect! Great job!!

I am glad you tube is a repository of old and new videos.. this is 2021 and I am 69 and just starting to learn arduino. I found this a very helpful video.. thanks my friend I appreciate it.,

[bangmai]

Thank you so much for your great videos. I already bought many relay to do the same. I can't do it for long time. Now I follow your teaching and to get success. Wish you good luck sir.

[mikewelch]

Ahmad, you design and build some of the most useful circuits available. Excellent channel!!

[shaunsomaru]

Thank you Mr Robojax! You are always so clear in yoir explanations.. You don't rush your tutorials..

[decem_unosquattro]

Good explanation without a drip feed, fluff, obfuscation or ego tripping! 😀👍

[samwoo]

Thanks. This is real clear for us beginners.

[Spix_Weltschmerz-Pucket]

Me again, thanks to your awesome explanation, I build this! Kudos!

[Shibu]

Thank you for posting this. I would love to see a follow up video with the Arduino controlling a relay based on input to the Arduino. In other words if I press one button the relay would be activated for one second. If I press a second button the relay would be activated for 10 seconds and if I press a third button the relay would stay activated unless a separate signal told Relay to shut off.

I am trying to control an AC motor that will raise a platform to various heights.

[grantfielder]

Thank you sir, you help to make my project work. Great lesson!

[dtanco]

Simple and concise explanation, best I've seen

[brain-circuit]

Very nice and helpful videos.. Finally found a channel to learn arduino in a very easy way.. Thanks man..

[tbmm]

Thanks! I was wondering how to connect a relay to a solenoid valve for pneumatics!

[StephenBoyd]

Much appreciated. I got my relay working and I am very happy.

[suhaimiyusoh]

Thanks. This is real clear for me as beginner

[mcdjacedad]

hi mate sorry for asking this you should of use Bootlace ferrule, not solder, solder well melt.
