so I'm new to all this Arduino stuff and have been trying to get into it, starting off with a simple project/test but have been having some issues. I followed the set up the book provides, and am powering the Arduino through an usb cable with my Laptop. The Arduino turns on and works fine but the LED on the breadboard will not turn on. Its connected to the Arduino and I believe I connected it to the right port ,5V and GND right? Anyways, I will leave some pictures below so you guys can see what I'm talking about.

Here's the set up they have in the book


Here's a pic of the Arduino


And this is how my setup looks

    I don't think you quite understand how a breadboard works. The components and wires have to line up. – Majenko Jul 7 '18 at 15:52
  • Not really no, the book didn't specify where to put certain things or at least not that I read. So all I have to do is line them up? – Daniel German Jul 7 '18 at 16:10

    A breadboard contains little metal strips that join the components together. They are all in a straight line going from the outside to the middle. Eg, pins 8A to 8E are all connected together. – Majenko Jul 7 '18 at 16:15
  • Thank you! feel kinda dumb now, the LED turns on, but the button or switch does nothing when I press it it should be turning it on and off but it doesn't. Is it the same issue? – Daniel German Jul 7 '18 at 16:28

    Your switch needs to be turned round 90 degrees. The pins on each long side are connected together - the button operates between the short sides. – Majenko Jul 7 '18 at 16:40
