Science Buddies: "Ask an Expert"

I was trying to recreate the refreshable braille system project posted in this website but i keep running into issues. i tried changing up my circuit but it still doesn't work. I'm using 12V solenoids with 0.4A. i cant even get one solenoid running. I've attached my new circuit. I'm using an IRLZ44N MOSFET.

I would really appreciate if someone could let me know what problem I might be running into

Can you please post the photos of your circuit and describe what is happening so that experts can best assist?

Thanks,

I'm sorry i cant figure out how to post images here, which is why i've attached the tinkercad link of my circuit instead. As for whats happening, nothing is. that is the problem. my solenoid wont even budge.

If you've built an actual circuit that isn't working, we would need to see your actual circuit. Just seeing the Tinkercad version doesn't rule out what may or may not be in place in the physical circuit.

To add an image, click "Attachments" and then click "Add files." Select your file to attach it.

Hi - I tried opening your Tinkercad link, but I get "Sorry, that page is missing." You need to change the circuit's privacy settings to "share link" or "public" first - if it's left to private, only you will be able to view the link. If you do that and repost the link, I can look at it to see if there's anything wrong in Tinkercad, but it will also be good for us to see pictures of your physical circuit as Amy mentioned.
