Introduction media type="custom" key="543349"
= = Video 1: Introduction of Wiki Resistors are used to reduce current in circuits. Capacitors store electric charge and smooth the current. Intergrated Circuits (or ICs) are microscopic chips made of silicon and surrounded by plastic, metal, or ceramic. Speakers and buzzers make sound. They are external parts of the learning lab. Breadboards are what the circuit is built on. They connect all the parts and contain the battery and ground. LEDs emit light. They are also external pieces. Wires connect things.

LED Flasher
- Function of the circuit: The function of this circuit is to make the LED flash. - Components used in the circuit (listing with basic definitions): An LED (or light emitting device) emits light and must be installed the correct way. Intergrated Circuits (ICs) are microscopic chips made of something such as silicon and surrounded by plastic, metal, or ceramic. Wires are used to connect things. They are metal surrounded by rubber. They come in different lengths. Resistors resist the flow of electricity. They can reduce the current before an LED. Capacitors store electric charge and smooths the current.

- Explanation of difficulties encountered while creating the circuit: The difficulties were making sure no wires were touching and making sure things were installed the correct way. The breadboard being used was fried, so the whole circuit had to be transfered to a different board.

555 Circuit
- Function of the circuit: To allow a buzzer to sound, by connecting the various parts the circuit was the goal of the circuit. - Components used in the circuit (listing with basic definitions): A 555 intergrated circuit was used, which is a micropscopic chip surrounded by metal, plastic, or ceramic. Resistors 1, 2, and 3 were also used to reduce the current. Capacitor 1 was also used and it smooths the current. Several different wires were used to connect things. A buzzer was used to make a buzzing noise. - Explanation of difficulties encountered while creating the circuit: Using the buzzer and external tools, while keeping the circuit together was one problem that was encountered. It was also hard to connect springs to each other. - Multimedia (Images, Interviews, Videos- make sure to title and number them) Image 3: 555 Circuit from the sideway Image 4: 555 circuit from Above media type="custom" key="543293" Video 3: 555 Circuit Interview

Missing Pulse Detector
- Function of the circuit: The function of the circuit to make an LED flash in a rythamic pattern. The potentiometer can slow down or speed up the pulses. - Components used in the circuit (listing with basic definitions): 2 555 intergrated circuits were used, which is a micropscopic chip surrounded by metal, plastic, or ceramic. Resistors 2, 4, and 3 were also used to reduce the current. Capacitor 1 and 2 were also used and they smooth the current. Several different wires were used to connect things. Q1 is an integrated circuit. - Explanation of difficulties encountered while creating the circuit: Keeping the circuit together was one problem that was encountered. It was also hard to place things correctly. - Multimedia (Images, Interviews, Videos- make sure to title and number them) media type="custom" key="539825" Video 4: Missing Pulse Interview Image 5: Group 3 with Circuit Image 6: Missing Pulse Circuit Up Close
