Just read what’s on the relay. For 5V it may hold up yo 3.7V. Unless you try, you will never know as not all relays are produced by the same manufacturer.

Do you need to electrically protect or isolate the Arduino from the load controlled by the relay, or from the relay itself? I've seen it done with optocouplers to isolate but you're not using it, so I'm confused. Maybe depends on the load? I want to control a 300 watt 120v AC fogger.

@robojax 3 жыл бұрын

the AC portion of the relay is already isolated. This relay module has driver that drivers the relay. In some instances people prefer to isolate the driver and power it up from separate source. If you look at the rating of relay and do the math, at 120V it can handle about 1200W . It is your decision. But I would use this relay if I respect the rating of of relay and not overload it.

Greeaaaaaaaaàaaaat, I have a question, Can we connect ACS712 and a relay with a same load, i.e to check if the current flowing from the load exceeds a certain limit, then the load can be disconnected or turned off automatically through the relay.?

@huzefaali9374 4 жыл бұрын

Very informative question

@robojax 4 жыл бұрын

with ACS712 the variable "current" is holding the current. if you watch both videos fully without skipping, it would very easy. if you don't want to learn then hire someone here www.upwork.com/ and pay someone to do it for you. Choice is yours. I have provided for free so you watch and learn. Good luck

This bothers me somewhat. I need to power the arduino separately from the bulb? I already have a cable going into the wall. Is there a way to split the bulb wire into parallel and run it through a ace converter and power the arduino which controls the relay and the other branch of the wire? So there is a single source of power?

@robojax 18 күн бұрын

In this video it is assumed the that you know how to power your arduino board. It is very simple. Connect it to a usb. Now if you don’t know that either, the arduino board has a usb connector which you can program via computer or power it up.

@anggadamanik8506 4 жыл бұрын

You're using NO and COM on relay. So, the relay would be in "Closed" state if there's any signal from arduino. But why the bulb is ON when the signal is LOW in the program. LOW signal=0V means no signal, since you're using NO, the bulb shouldn't be ON. Please help:(

@robojax 4 жыл бұрын

I have explained it that the relay module is "low trigger" meaning it need LOW to turn ON and HIGH to turn OFF.
