Hi, i am having a weird issue, the relay is switching on as soon i declare the pin as out pin but the relay is not switching off. Can you please suggest a solution?
I wander if I could use a pico w and use a wireless router. Could i use this idea to take place of a garage door switch ( like a door bell switch ) . To control my old garage door using my phone ? I have the components for it .
Yes, we actually released a video doing exactly that when the Pico W was released, the only concern with the project is security as anyone with access to your Wi-Fi can open your garage. Although if you manage to figure out the project it's probably not too much trouble to add some extra protection like a password on the garage control web page. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-bIBQKl_Sots.htmlfeature=shared
I was able to drive a 5V relay on the pico's GPIO with a VERY similar looking relay (don't have the d.sheet) BUT it crashed the serial communications to the pico
hi! i'm getting no snappy sound when i run the script (coming from the relay). Furthermore, I'm not capable of burning the LED even though I connected it with no resistor to the wire coming from the Common slow of my relay. The ground is connected. Oddly enough the red light from the relay dims a little when I the signal gets sent... Am I being a dummy or is there maybe a relay power issue going on? Lovely video, thank you for posting it! :D
The best place for technical help is on the forums. There you can share a photo of your setup and we can debug the circuit properly: forum.core-electronics.com.au/
I copy exactly what you done and the output from GPI 16 was not strong enough to activate the 5V relay (the red led is on but the green one remain off). I understand I should use UL2803A to elvate the output signal from 3.3V to 5V
it's common to switch a load on the low side because this is often how it's done with transistors (NPN, or N-Channel MOSFETS). In this case it doesn't really matter though!
