Topic: Relay curcuit not switching on (Read 2 times) previous topic - next topic


Can you show a photo of your setup ?
One that shows all components and what wires go where.
Could be all kinds of things causing your problem.
Also please tell us what relay you are using (what is written on it, or also a photo of the text on it).
Have a look at "blink without delay".
Did you connect the grounds ?

so what i was trying to explain is that my circuit works fine,

So what is the problem?
but for some reason the relay does not turn on and off

Then the circuit is not working fine. What makes you think it is working fine?


@ MAS 3
I have 2 setups, with 2 different relays.
As of now I took the cord which runs on the relay off, but of course when i was testing it was connected.

3 images are attached:
     1 (blue relay) is simpler and connected to a breadboard (soldered)
     1 (relay not seen) is the same and connects to the relay in image 3. This does not use a breadboard as i thought i might have had an issue with the soldering (I don't)
     1 image of the 2nd relay - gray relay


What I mean the circuit is working is that until the relay (if you look at the gray relay picture i am referring to the point where the wires connect to it in the image), I can control the 5V or 0V making its way there on command.
