@@mickadams4471 likewise Mick, always a pleasure to see your face popup on my TH-cam notifications 😁, how's your scope treating you? Im pretty out of touch with mine but I do enjoy looking at it everyday 🤣

@@foadgaroosi4096 thanks bro ♥️

@adamjallow2890 I did this first year of university

@@aaronfrye1195 yeah I think I'm still on the fence but want to support the movement. I'm desperate to use it a lot more!

@@TheMachtFamily haha I think you mean eggsy but autocorrect changes it to eggy 🤣 I'll take that. Good luck with your grandson! I can't wait to start teaching my kids this stuff!

Then the library is already installed, use 5V instead of 3.30V

@@lucas.ludziejewski sadly I'm still using these horrible things, I call them single use resistors now

@@HamedAdefuwa Looks like everything now is getting low-cost, single-use. This is the "ecology" they are talking about. Take care and thx for your videos.

It's a normally closed signal we use to send back into the system, so in my case I've got it wired into input 1 of my PLC, that's the signal my PLC is reacting to when I press the estop. My bad I should have mentioned this in the video. I missed out a fair bit actually lol

@HamedAdefuwa so if I have a signal in my plc from auxiliary contacts, it means that the safety relay is either turned off or faulty? But how can I differentiate between these two situations?

I guess you can't with this simple safety relay without also sending one of the NO contacts into another input and watching them change over. Which I have done before. Under normal operations, the safety relay is active, meaning the NC contact is open. In this state the PLC receives no signal from the NC contact, indicating the system is healthy. Feels backwards I know lol but it works.

They're in parallel for safety or redundancy. When the status is OK, 41/42 is open. If there is a fault, 41/42 is supposed to close. If for example K1 41/42 fails to close, you have K2 41/42 as a backup. For the same reason the NO contacts are in series. If K1 13/14 fails to open (contacts fused together), you have K2 13/14 as a backup.

@@hanitessieh7449 yeah you can't block TH-cam ads without blocking TH-cam itself

@@JeremyCook Short wires reduce inductance because inductance increases with wire length. Inductance comes from magnetic fields generated when current flows; longer wires create larger magnetic fields and more inductance. Thick wires matter because they have lower electrical resistance. Lower resistance reduces energy loss and minimizes voltage drop, which helps maintain accurate current measurements when using a shunt. Thick wires also spread the current over a larger area, reducing the magnetic field strength and thus lowering inductance.

@@HamedAdefuwa Thanks!

@@the_fall1n.1 portenta was their original open PCB one I guess. Now they're going after more industrial

@@Somatom_Man I love it, that town needed the bridge so bad. When I first arrived there in 2023 it was horrific. The looks when it's down are beautiful. When it's up in the air, it's a bit weird lol massive gap between the road in the air and the floor.

🤣 here's an interesting idea for you, perhaps these videos aren't for people? perhaps I do these for myself? 🤔 Cheers for your opinion anyways. I'm currently planning a video on safety relays after losing 2 hours on one the other day so I guess for numptys like me, we need more than a datasheet.

@HamedAdefuwa Well If Not on the datasheet on then on their application notes for example microchip or stm microcontroller or some plc manufacturers website. Almost every arduino plc source code is open. That is why peoples are not interested on this type of contents In youtube.

What part did you miss about this not being for other people? I do videos on what I'm working on for myself. To concrete ideas and to document my journey so when I'm 70 I can look back and laugh. If anyone else wants to follow along and laugh or learn something, great. As for people like you, I hope you hit your daily quota of criticism. ♥️

@@HamedAdefuwa I am not criticise You. I am telling the true. This is not an engineering. Technicians does this things in Europe. Unfortunately uk education system is pretty much a joke Because In a high school they are not teaching profession at all. Again i not blaming an individual. Hope You understand this.😃

@@HamedAdefuwa Another thing. One of your previous video you admitted advertising a product. Unfortunately now very hard to believe you not doing a same thing. But again no personal things.

@@simonprice-hn3sx I've been using the IDE, it's alright. I've definitely got codesys on my radar so can't wait to give that a go.

This could be due to a potential conflict between Arduino and Finder. Since Arduino plc ide is bugy and I think it is unfixable. So Finder took the decision to go with Codesys to save its image.

Oh wow that's interesting. I wouldn't have thought anyone would consider finders image related to the IDE, I automatically assumed it was all Arduinos fault and Finder just did the hardware side of it all.

​@@HamedAdefuwaImagine yourself as a CEO of a company known for its quality products in the industry and found its name on a product that can't meet its quality standard. And the worst of all the cause of the problem is not your fault. It is a good respectful decision by Finder and it indicates their focus on the customer experience and the flexibility in the company management.

I agree with you so far, I've got a decent video coming out tomorrow night where I drive all its IO and I'm enjoying it a lot more. I'd love to try use it on a real system to be honest. Cheers for the controllino call, their website looks decent. Looks like I can get one on ebay for £250, open source software as well

fore some reason my arduino is too weak to power all the ground

@Roninga6 Yo I had this problem too and then I realised my 74HC595 Shift Register was on the wrong way the end with the semi circle should be facing towards the LEDS and this fixed it for me. Good luck!!

@aliamirouche4796 i had that too
