- Explanation of difficulties encountered while creating the circuit:

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

Led Flasher
- Function of the circuit: The function of this circuit is to make a LED flash.

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


 * 1 555 integrated circuit- help control current in circuit


 * 4.7k, 10k, 1k resistors - resists the flow of electricity


 * 10 uf capacitor - creates a pulsing electrical signal by storing power and releasing it at a predefined rate


 * led- produces light


 * wires- transports electricity

- Explanation of difficulties encountered while creating the circuit:

There were many difficulties wile making the circuit. The first problem we encountered was a faulty circuit bored witch prevented the circuit from working. The second problem we encountered was misplaced wires on the circuit board. The third and final problem we had was putting the one way LED the wrong way

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

555
- Function of the circuit: The function of this circuit was to make the Speaker emit a tone.

- Components used in the circuit (listing with basic definitions):
 * 555 Integrated Circuit- a common place to put all the wires
 * 1k, 10k, and 100k resistors- to control the flow of electrisity of the circuit
 * 1 uf capacitor- creates a pulsing electrical signal by storing power and releasing it at a predefined rate, makes different frequencies in this circuit
 * Speaker- Emits a tone when electrical current runs through it.

- Explanation of difficulties encountered while creating the circuit: We had several misplaced wires that helped complicate the circuit. That was all the trouble we had.

Random Number Generator
- Function of the circuit: The function of this circuit is to generate random number. - Components used in the circuit (listing with basic definitions):
 * 4049 and 4017 Integrated circuits- help control current in circuit
 * 4.7k and 1k resistors - to control the flow of electrisity of the circuit
 * LEDs - emit light
 * 470 uf and a 0.01 uf capacitor- creates a pulsing electrical signal by storing power and releasing it at a predefined rate
 * Wires - to transport electricity

- Explanation of difficulties encountered while creating the circuit: We Misplaced wire and we put the ICs backwards. - Multimedia (Images, Interviews, Videos- make sure to title and number them)
