This relay draws 66mA current in total when it is ON. So it will have no affect on Arduino at all.

Just found out that the 5V regulator of my arduino mega was not working anymore. I have a 12V power supply hooked on it, but the arduino only worked when the usb was hooked as well. I have to confess that I am not 100% sure it was the relay module the responsible for the broken 5V regulator, but as soon as I hooked it up the arduino started behaving strange. The problem with this relay module in particular is that it has no optocoupler. If I can give one advice to everyone is the following: DO NOT USE A RELAY MODULE WITHOUT OPTOCOUPLER WITH ARDUINO.

Hi, you can read values between 0v to 5v. If your values are in between 0-5 volts you can read it. So to measure AC voltage, just use resistor voltage divider to reduce it by 10 time or 20 times and then measure. If you want to know how to read voltage, watch this video kzfaq.info/get/bejne/ish8l6SC1auYmnk.html

Yes it can as long as the power of the device is not above the 10A. So the deice should be under 2000W. Ready the current your relay can handle. it should show 10A or 5A. then multiply Voltage (V) x Current(A)=Power (Watt)

Why high and low have inverted result on relay? With High is off, with low is on. Can i use it for 1200w device? ( 220v)

@robojax 6 жыл бұрын

It is because you have connected your wires like that. You have 3 terminal (let's call it ABC) to connect your 220v. You have connected One to center (B) and one to the other side (A) . Simply keep the center wire (B) and change the position of wire (A) to (C) which means move it to the terminal which were empty and it will inverted now.

But when the relay is turned on, the bulb does not get power. I don't see voltage at NO when relay is on. I tried with NC. Then the bulb is powered-on but it never gets switched-off. It is always on. Thanks in advance.

@robojax 6 жыл бұрын

do 2 things. first. the two wire that you connect to relay, connect them together (to switch it ON) and then (carefully without touching it) connect the power to the bulb to make sure it turns ON. 2-using continuity tester on multimeter (which buzzes when you connect two prob) or if you don't have this option, use it as ohm meter and check the two terminal of relay where you connect the bulb. you should read zero OHM. there can't be anything else. you should find problem either in step 1 or in step 2. There is no more help I can offer.

@@robojax hey I am programming a sanitizer dispenser with IR sensor, Arduino Nano,Relay module I want a timer limit for each dispensing (I mean, even if someone puts hand under IR sensor for a long time continuously it should only dispense for 4 seconds) I wrote void setup() { pinMode(8, INPUT);// set pin as input for IR sensor module pinMode(9, OUTPUT); // For relay module } void loop() { bool isON = false; int detect = digitalRead(8);// read obstacle status and store it into "detect" if(detect == LOW && !isON){ isON = true; digitalWrite(9,HIGH); delay(2500); digitalWrite(9,LOW); }else{ digitalWrite(9,LOW); } } But it's not stopping after 2.5 seconds even if put my hand for long time Is there any mistakes in my program Please help me....I am stuck I hope you will help me please...

Hello! Does anyone have this relay module for fritzing? Where can I find it to import it in fritzing?

@Dean.Michael.Winchester 2 жыл бұрын

Why my motor still works when I connected to NO? Does the relay works when the circuit have no electricity? I mean, I use 2 sources, from USB and from 9v battery, the relay doesn't light up if the electric from USB not connected and the board is not online, but the motor still works as it use the battery source

Yes it does turn something ON when it has not power. You can use it to turn OFF something or turn ON. You may need to watch this video which is part of the course kzfaq.info/get/bejne/hJOoldulrK3TeKs.html

@@robojax so, it doesn't matter if I use relay or not, the connection will always be ON? Even if I connect to Normally Open? I though relay is just the same as the switch with NO and NC hmm
