Week 1

After I set up my breadboard and learned about what all the different components were, I worked on lighting my LED. 

My first try was wrong for a couple of reasons: (1) my LED was facing the wrong way - anode needs to connect to ground bus and cathode to power bus (2) I put a voltage regulator with the Arduino, which wasn’t necessary since the Arduino already uses 3.3V. (3) I incorrectly wired the Aruino to the power and ground buses. After fixing it, I got a working LED!

I tried out some other variations of lighting the LED. When I tried to light two LEDs, they wouldn’t work. When I put three switchbuttons in series, it worked.
