P&PI PROJECT 2 - TUTORIAL 2 - Pushbutton

This post is relating to the 2nd tutorial for my project where I have to create a push button. I connect a button onto a breadboard and once the tutorial is complete, I should be able to turn on a light by pressing the button and turn off the light by letting go of the button.

It took me a while to figure out what the proper way to use a breadboard is. As the 2 tutorial pictures were different in design I was worried that I wouldn't be able to figure it out. However I found that only certain parts of the connections that I made had to be specific. Namely the a1. b2, c3, etc, row.
I could actually connect the other wire to any of the negatives and it would still work. However if I put it into a positive, it would cease working.

I took the photoresistor out and although the light would only turn on once I pushed the button, it refused to turn off after I let go of the button. It was from this process of messing around and taking them apart that I was able to understand what they were used for. I am finding that the majority of this assignment doesn't make sense until I mess around with the board after tutorial completion. I will continue to try out this process.
