Problem with small solenoid

Hi !

I’m completely new to Arduino and electronics…

I’m trying to drive this small solenoid :

and “micro” ones :

from an Elegoo Uno with a power supply and L293D chip (potentially to drive a bunch of them at the same time eventually, my understanding is that one chip can handle four solenoids in theory…

But I can’t manage to make the regular one move (I still need to solder better cables to the micro ones for testing) with this setup.

Any idea what I did wrong?

Thanks !

You need a common GND between the Arduino and the breadboard.

Make sure you have the correct voltage to drive the solenoid.
