Over the past two classes we have learned much about electrical circuits and how they work. We began with a very basic circuit: one that had an LED light that was connected to a 3 volt battery. Then we moved onto using 9 volt batteries with resistors. We learned that by itself a 9 volt battery is too powerful to power an LED as it will burn it out, but with a resistor a 9 volt battery only provides enough to power the LED. We then learned how to use breadboards and switches and how they both worked. We learned that with a breadboard you can power multiple LED instead of just one and that a switch allows you to decide when you want to power something. At the end we put all of this knowledge together which resulted in a breadboard powering multiple LED lights that had both a switch and a resistor.

Here is us powering a breadboard with a 3v battery:

Here later along is us powering the breadboard with a 9v battery using a resistor:
