im new to arduino but like it from the beginning.
I have a problem with my first project including the SRD-05VDC-SL-C relay
I have wired my nano with a button and the relais. When i push the button the relais should open a magnetic valve powered with 12V. 12V Batt and the magnetic valve works fine when directly connected. When i push the button the led on the relay powers up but the relay didnt open the valve. Altough tested the setup with a multimeter (MM- to relay COM, MM+ to power-, power+ to relay NO)
Btw i followed this vid https://www.youtube.com/watch?v=mNw55WjbDns
At first i thought the relay is broken, but the new one shows the same error...
