- Components used in the circuit (listing with basic definitions):

- Explanation of difficulties encountered while creating the circuit:

- Multimedia (Images, Interviews, Videos- make sure to title and number them)

Flashing LED
- Function of the circuit: Makes an LED flash

- Components used in the circuit (listing with basic definitions):
 * Integrated Circuit-A small chip containing hundreds of thousands of transistors and diodes
 * Resistor-Used to resist the flow of electricity
 * Capacitor-Controls timing and duration of flashes
 * LED (Light Emitting Diode)-A diode that emits light
 * Wire-Carries electricity

- Explanation of difficulties encountered while creating the circuit: Fitting the LED in the right place and finding the right resistor out of the whole pile.

Digital to Analog Converter
- Function of the circuit: To convert digital signals to analog signals

- Components used in the circuit (listing with basic definitions): > > - Explanation of difficulties encountered while creating the circuit: One of the intergrated circuits was broken, leading to having to replace after having put all the wires. There were so many wires it was sometimes hard to fit them without messing something up. > > - Multimedia (Images, Interviews, Videos- make sure to title and number them)
 * Integrated Circuit: Transistors and diodes compiled together in one component.
 * Resistor-Used to resist electricity
 * Capacitor-Control timing and duration of flashes
 * Wire-Carries electricity
