Day 6: In which I learn to drive higher loads with a microcontroller

This Christmas light is much larger than an LED and requires more current than the microcontroller and the wall plug is able to provide. We used a capacitor to make the current larger. This was able to drive the Christmas light and make it bright.

This uses two capacitors to make what is called a Darlington. This uses two capacitors to amplify the current twice. In this setup, we also used a diode so that if there was a motor instead of the Christmas light, there would be no back EMF to hurt the components on the board.

The final part of the packet was to finally drive our motor. Now that I understood how to drive higher loads other than an LED, I can get to finishing my project. The only problem that I am finding is that the motor is very slow. I will have to figure out another way to do that later. For now, I want to focus on the programming side of things.
