Bhai NodeMCU ESP8266 k sath external power supply 5v module ki jarort padegi kya 4 channel 5v relay H I want to on off my led bulbs 12watt Also Ceiling fan With wifi
Thanks sir, ye faeda hota hai jitni jaankari ikatha kar sako karne se. Sir, bata nahi sakta kitna pareshan tha me kuch dino se. I lost the jumper somewhere and my relay was not switching on and off though the LED was blinking all four of them. I thought it got burned because I tested it on the switchboard earlier with a DIY wire, creating a spark. But you had the proper knowledge of the Relay board and explained well the optional feature to use it with 12 V by removing the jumper. I lost the jumper somewhere in the house, I am not sure I am going to find it because it is like finding a needle. So I will simply short circuit and solder the VCC and JD-VCC so my job will be done. Thanks again. I subscribe your channel now.

This is a hight voltage device ,so if anyone doesn't understand its current, voltage.. limitations cleary then it can be dangerous .
I want to control 4 switches in my home . I will be wiring relay board into my electricity board. My question is : is it ok if I directly power the relay board with Arduino power ? I don't want to pay extra money for a separate 5v supply . Will that be OK if all my 4 bulbs are on at a time ?
That was a great video. Immediately subscribed after seeing the quality of video and the content. Thank you for sharing. Please keep making new videos !!
Very nicely explained. Mai nodemcu8266 use kare ke Ek 3 light aur ek fan control unit banana Chahta hu. Mere 2 doubt hai.. 1.agar mai relay me 220v live wire ke jagaha par neutral wire connect karta hoo to kya hoga.. mujhe lagta hai live wire connect Karne se acha neutral wire ko Karna.. aap bataye konsa option better hai. 2. Celling fan to regulate Karne ke liye kya use kare

Hello Friends, I need some knowledge base on USB relay application where Relay can send instruction to PC and run application. For e.g. I have a 4 channel USB relay. Relay is connected with push button. Relay device is connected with computer via USB port. My objective: - If is press relay push button 1 then a computer program will start in my computer. If is press relay push button 2 then a computer program 1 terminate and program 2 will start in my computer.
Hi bro plz can u help me about password based home automation. I am making and need code of the circuit but not found on the web have used 4 channel relays. Thanks
I am quite new to relay and arduino. I have made the connection as mentioned in your website and this video. Uploaded the program to arduino. I can see small LED blinking on relay every 3 seconds however no noise is coming from the relay and bulb is also not blinking. Its 5VDC relay with 10A 250 VAC reading.
Bro relay low signal per work karta hai Iska MATLAB jab ham Arduino k sath connect karenge to relay starting me start hi rahengi Pleas give me solution
Help me,, Sir please, Mera realy operate nahi ho Raha realy boad me on/off led indicator dikha raha par realy on nahi ho raha relay kharab nahi h maine test bhi kiya. Give me solution sir
Hello frnds.... i am getting uploading error while uploading arduino sketch through Android app arduino drive.....even i select right board option UNO...plz help me out.......i am frustrating........start mein upload horaha tha ab nahi hoparaha haii...plz help me out
Jab arduino ka output low hota hai tab relay on hota hai aur jab arduino ka outout high hota hai tab relay off hota hai. Is behaviour ko ham change kar sakate hai kya?
hii ji maine arduino home automation banaya hai.. to usme muze ek problam hai ,,. ki jab bhi bijli sali jati hai, aur jab vapis aati hai to mere arduino board ki digitel pin automaticly relay ko activet kar deti hai to,, iska kya karu

how to power relay from external source and not arduino board.
for using it 24x7
What happens when i gave relay 9v ,dose module. Burn
I am quite new to relay and arduino. I have made the connection as mentioned in your website and this video. Uploaded the program to arduino. I can see small LED blinking on relay every 3 seconds however no noise is coming from the relay and bulb is also not blinking. Its 5VDC relay with 10A 250 VAC reading.
+Raj Pachori Are you providing the external supply to relay or through arduino?
RoboShala through Arduino. 5v supply. And Arduino is connected to 9v battery exactly as shown in your video.
RoboShala thank you for a quick response. There was some problem with relay. I got the relay replaced and it started working now.
