I purchased the Raspberry Pi YouTube Workshop Kit from Buy a Pi.com a few days ago. I have a B+. But when I completed tutorial number two, LEDs On and Off, only the LED on the right turned on. Then I swapped the lights to see if one was burnt out and again only the one on the right turned on. Then I swapped resistors (yes, I'm using the correct ones) and NEITHER turned on. Now nothing will do anything- no lights on, no circuits working, it's all so confusing. does anyone know what happened and how I could fix it? I can't post a picture because I only have three rep, but I added link below. I'm absolutely sure it's wired properly.
Please help me, I need to do a presentation on Friday with the board.
Some links you might need: Purchase website- https://www.buyapi.ca/product/raspberry-pi-youtube-workshop-kit/
Scroll down to lesson two. The video and wiring diagram are there. I'd give the links but I need 10 rep.
