Here is my homework for week two, created using instructions and schematics from Joel Murphy’s Site. We are learning about capacitors and transistors. Capacitors make sense, transistors I’m still a bit fuzzy about but starting to make sense. The first circuit is a transistor toggle switch, basically when you hit the switch it uses the PNP/NPN transistors to redirect the flow of electricity to the other LED. The second is a photoresistor and a potentiometer hooked up to and LED and a transistor, which allows you to turn on/off the LED. This one makes sense to me, the electricity takes the path of least resistance, so as the resistance of the photoresistor increases the electricity begins to move through the LED. The third is using a capacitor to fade an LED on and off.
