My Contribution in this project will be to mount a circuit that will be audio activated using LED, a transistor and a power source. This is how my initial thought of the circuit should look like.

After assembling the circuit above it didn’t work as I thought it would be which is to turn on and off responding to frequency of the music. I did some research and found out that the type of transistor used matter. Some also suggested using two transistors of type TIP31 one to control the left and the other to control the right of the circuit, which means it will be kind divided into two but all connected. All sides LED are in series which is a challenge in case one break which means the power will be cut for the rest of the circuit but I did found that LED “legs” are reliable to hopefully it won’t happen. My next circuit will look like this

Try to mount LEDs without a universal is becoming challenging, so I decided to buy one from Radio Shack. This will be easy because each wire will have its own connection I wont worry about them touching. The first circuit seems to be easy to make and when I did put everything on the universal breadboard, with a pre-terminated audio plug the circuit work its is suppose too.

After founding a working circuit the next challenge is to come up with a way LEDs can be connected together and be incorporated in clothing. The idea that came in my mind is to join many together by using less voltage which will reduce to heat and fire concern in case this is used in clothing. I know that in parallel circuit the voltage is equal through the entire circuit, which means I can light many LEDs connected in series bya same law voltage. But also thinking in a way the can be used on a cloth I found it not presentable to be in line. So I will mount both in series and in parallel of each other. Four LEDs will be connected, in series on two and parallel of two.

With this I am using same voltage to light 2 LEDs to light 4.
