Integrated Circuits
Introduction:
The Purpose of this project was to learn about circuits and electricity in a fun way. We got to integrate circuits into something we wear/use every day and then we got to use our article around school. Also, we want to highlight the importance of circuits in our everyday lives. My group chose to integrate circuits into bags because we use bags all the time, especially at school so we can show off our finished work. Also, bags don't typically include circuits, so we could use our imagination. Once I decided to do a bag, I planned out what circuit I wanted to integrate into it. I choose to put an E out of LEDs because it is the first letter of my name. My circuit contains 9 red LEDs, a 9 V battery, and a switch. The photo below is a picture of my final product.

Circuit Description:
The parts in my circuit are, 9 light emitting diodes (LEDs), one switch, copper wire, a 9 Volt battery, a 680 ohm resistor, and got glue. Below is my circuit diagram and my real circuit while I was working on it. My circuit is a parallel circuit, with means that each LED is hooked up to the one previous to it, rather than to the battery. I chose a parallel circuit because then the bulbs would stay brighter. My battery will die faster though, since the parallel circuit draws more current from the battery than the series. I used a resistor in my circuit because the LEDs on their own draw too much current from the battery and if I didn't have a resistor (a device that resists the flow of current in circuits) then the LEDs would all burn out. I calculated the power in my circuit by multiplying the current by the voltage because of Ohm's law with states that Power is equal to current times voltage or P=IV. So my current was 10.4 and my voltage was 8.87 (I measured the power and voltage with my voltmeter). So my power is 92.248 mili-watts.

Final Product
What I really liked about my final product is how my bag has a finished look to it and you can not see any of the wires. I also like how I added hot glue to my circuit on the inside so the letter is clear and it didn't fold up like I was worried it would. Also, I like how my bag is usable and I will use it in the future. The picture of my final bag is at the top of this page. What I would have done differently is work harder on my original circuit diagram so that I wouldn't have to re-do it later. I also would have gotten my materials sooner so it I could plan design my circuit based on the materials I already had. A question I still have is why do I only need one resistor even in a parallel circuit.
