Dear student2331,
Without additional information, it is difficult to provide help. Are you working on this Science Buddies project?

If so, I would start by making sure the power supply is good. Check that the batteries are good and in the correct position (+/-). Then, consider checking the resistance across each component with a multimeter. If you don't have a multimeter, then try replacing each component, one-by-one.
A photo of your breadboard would also be helpful.
Best regards,
Dr. Payne
