I have tried this but it doesn’t for me. I have 5v relay module as soon as I connect vcc to 5v pin, ground to ground pin and in to pin 18 which is set to out both relay lights glow. Even if I change pin status of 18 to dh or dl it doesn’t control relay at all. It always glows both the lights. But if I remove and connect pin 18 then it turns on and off the relay state. I have no idea why pin 18 high and low not controlling the relay. Any idea on this? I am able to control led through same pin 18 by setting it high or low but bit relay. Thank you.
Hi! This is a great tutorial, I followed all your steps but sadly my relay is not switching. Do you know why ? It just lights on and off but it is not switching.
muy buen contenido, pero tengo una duda, mas bien es un problema, al momento de ejecutar cualquier codigo de rele en python on raspberry, me sucede que se activa el rele(osea en automatico), pero ya no se puede desactivar, además ya intente de distintas maneras, y nada, espero que me pueda ayudar con eso. por cierto se ha ganado un suscriptor :D
You'll have to use a ULN2803 driver for connecting 12v relay. Raspberry pi output goes to input pin of ULN and the output pin of ULN acts as sink driver for relay coil.
This is a single channel relay module. Based on where you are just search on amazon for "single channel relay module" and you'll most probably get it :)
hello, I can't speak English. I'm using google translate. I'd like to ask. I get the message "RPi.GPIO as GPIO no module" what is the solution? I have installed but it didn't work. Please help me 🙏🙏🙏
Awesome sir

Hi
Please whatsapp ur issue with pic / video on +919404865609, I'll be glad to assist
hi ty for the vid. the relay act as a switch and a volt divider between the power supply and the R-pi?
because of the 3.3 volt limit in the R-pi
ty.
yes, relay is a switch, which turns on using the transistor which operates on 3.3v output of raspberry pi
sir which software are you using for this schematic
Hi, the videos are created using Fritzing
@@Kitflix nice thanks!
Excusme sir, why importError : No module named RPi.GPIO. even though I already installed the library. Thanks SIr
Can i get your ppt file
is it possible to switch on and off a mosfet IRF840PBF ?
Yes, an N Channel MOSFET can do that. But only for DC Loads and not for AC Loads
@@Kitflix i tried it with 470 volts AC and it works

Thank you, am sorry for so late a reply. If you can give me your relay problem in detail (connection screenshot, code) I'll be able to help in detail
@@Kitflix Tengo el mismo inconveniente
guys make sure your vcc must connect to 3 volt not to 5 volt otherwise it will not blink
Dont forget to connect resistor to LED
Hi can you tell me how to connect 12v relay to the raspberry pi
I tried connecting to 3v3 pin but the switch didn't turned on.
You'll have to use a ULN2803 driver for connecting 12v relay. Raspberry pi output goes to input pin of ULN and the output pin of ULN acts as sink driver for relay coil.
what relay is this? can you send an amazon link

@@Kitflix I already found a relay that works. Thanks though

You're welcome!
Hi! My relay works fine but the light stays on constantly. HELP!!!!

please elaborate your problem and send me a mail :)
Same to me ☹️
@@RRB47tv Bro you need to buy a 3v relay instead. Works like a charm for me now but I have to sell the 5v...
