During class today, we watched several videos about how to make an LED light up, how to make a circuit, how to add a resistor to a circuit, and how to add a switch to a circuit. My favorite part was making a circuit with a resistor, because although it seemed complex, it was rather easy once you got the hang of it. I connected all of the wires and the 9V battery to the bread board, and then I put the resistor adjacent to one of the wires. After this, I placed the positive LED leg in the same row as the resistor and then placed the other leg in another column. Finally, I added one more wire and turned the LED light on! To expand on this, I decided to add a switch that could control the light and turn it on and off!
