Science Buddies: "Ask an Expert"

Hello,
I need help urgently. I am doing the Dealing with Diabetes: Road to developing an Artificial Pancreas experiment. My peristaltic pump turns on when I connect it to the Arduino uno, to check if it is working. However, whenever I connect it to the breadboard, which is what the experiment calls for, it doesn't turn on.
How can I fix this? Is it a problem with the Mosfet or computer code? I have followed all of the steps. Please help, I have to submit my project by this weekend!
Thank you

Hi - sorry you did not get a reply to this last week. Were you able to get it to work? There are a lot of things that can go wrong with an Arduino circuit, so it's impossible for us to say what's wrong without seeing your circuit. If you can upload well-lit, in-focus pictures of your breadboard with a top-down view so we can see all the connections, then we can help you debug. We also have an Arduino debugging video that you may find helpful: https://youtu.be/9GLaU-BCEQM. Sorry if this is too little, too late.
