Hello guys welcome to my minecraft lesson lets mine for diamonds and hopefully some iron and ore

Hi, thanks for the explanation. Important comment: When taking out the jumper to supply power from an independent source for relays, exterior pins shold be used (GND and JD-VCC). The VCC central pin is the same as the VCC in the other input as they are wired together through the pcb. I'm doing a little research since my board (NODEMCU ESP8266) works with 3.3V, and I want to try feeding 5V to the relays and 3 to the signal side. Would it be possible? Has anyone tried?

Very good video can you tell us how we can hook loads that exceed 30 volts DC so if I have two batteries that I want to toggle between and they're 36 volts wouldn't that 36 volts passing through there destroy the circuit how do we toggle between those two DC power loads and still get the electricity needed to run the application

Hi, that's why we use relay driver so enough power drivers the relay. voltage is one thing, the current (ampere) id different. Power = V*I, where P is power in Watt, V is voltage and I is current in A (Ampere). So you need to use relay module. or build your own relay driver shown in this video kzread.info/dash/bejne/gGGaqM1uYajIaNY.html

I have separate video on how to drive a relay See it here kzread.info/dash/bejne/gGGaqM1uYajIaNY.html . To keep the power of Arduino and the board separate, it is a good practice to keep the microcontroller and the power section separate. This increases safety.

Better use Wemos/NodeMCU board. ESP8286/32 boards have nice examples in Arduino IDE.

It would be somewhat safer to connect the ac neutral to the relay, being it is connected to ground, and can not make a circuit with ground, you would have to rember the line or hot wire is still live, when the circuit is shut off, so light sockets would still have a live contact, it would make the board safer to touch!

Hi, the piece of metal the current passing through the relay can handle 10A. At lower voltage works fine but higher voltage is prone to causing spark and for that reason you can't say at 250V it can handle 10A=2500W, we should then go back to 125V and use it for 2500W. 10A is the limit. Usually at lower voltages it works fine but can't increase it.

@@robojax there is a tutorial about coin acceptor my problem i dont have background with any source code in adruino so it is difficult to me to start this project i have the diagram for coinacceptor and your tutorial for controlling relays but my problem is i dont know how to start to combine those two the clue is on my hand but i dont have an idea to sketch the code

your link to the code goes to code to control the direction of a dc motor

@@robojax so i have watched the video. Three times. Have you clicked on the link to see where it re-directs you to? The code in your video, doesnt seem to match the code that the link goes to. Thats a statement.

Ye program work ni kar rha ha bhai. Log

I am unable to understand the DC motor connection at least you should have shared the circuit diagram

it is all about the code in Arduino. learn that and you will understand why I shown how to connect. I have shown all wiring. I just watched myself the video.

Can you please circuit send me plz.....

I have explained the wiring. this is very simple and doesn't need schematic. But you can draw it from the wiring I explained.

that would be too fast.

I've looked all over the internet and this is the closest I've found to a solution to my problem. My project has a 12V power supply using three 18650 Li-ion batteries on a charger board ( www.parts-express.com/dayton-audio-lbb-3-3-x-18650-lithium-battery-charger-board---module-12v-with-charge-protect--325-200 ). I need to upgrade this to 24V with another identical board using a 2-channel optocoupler relay I have from HiLetgo. I have all the components but have no idea how to wire them together safely. Can you help?

Hello, I can answer your question if I understand it and it is related to this video. I did not understand what you are trying to do.

@@robojax Thanks for replying. It's a bluetooth speaker kit with an amp that can handle 24V. But the kit only comes with the 12V board even though they do recommend upgrading o 24V. So I have to connect the two boards in series, with an optocoupler relay similar to the one in this video, in between controlling them somehow.

There is TWO HUGE mistakes in this video!!! FIRST MISTAKE: The 5V provided by Arduino is not enough to switch the relay because the optocuplor and the relay is rated at 12 Volts ! SECOND MISTAKE: The 12V for the optocuplor and relay must be provided on the pin named JD Vcc, not on the Vcc because the Vcc from left is connected with Vcc from right and you will put 12V on Arduino 5V and Arduino board will blow. I saw this video and I distroy one Arduino nano board. PLEASE PAY ATTENTION TO THE RELAY BOARD!

5V of Arduino can supply minimum 1A which is coming from laptop or desktop. Each relay will use maximum of 100mA so in total this will consume 0.2A so no worries.

NO not normally CONNECTED? that doesn't make sense. its normally closed and normally opened.

You are right too. It is just matter of perspective. In contacts and wires, "closed" or "connected" results the same thing: flow of current.

Robojax No not working with high voltage. the wrong words used is not your perspective. the wrong words can be result in people getting hurt or worse when working with high voltage. there is no liability in the wrong words you use just ignorance.

Midroll adds = Dislike Video You don't have to run midrolls, that is a fact, I let all adds run but will never let a midroll run if I can catch it, they are usually twice as loud , can run for an hour or more, literally. Not all of us are able to sit in front of our laptops, to catch disruptive midroll adds. Midroll adds encourage viewers to turn to add free subscriptions, which drives revenue away from content providers.

paid service is the best option. either pay and watch using premium or hire someone. you can't expect to get it absolutely for free. you give up something and get something. unless you are unjust person who wants something without paying for it.
