I had lots of fun in LED club because making the roaller coaster my group made was really cool. In my group I was the electrical expert (the one who hooks up the LEDs) so I liked my job. My group had a tub of water and they wanted the water to glow green so I hooked up green LEDs to the bodom of the tank and then I put a switch on it and then they lit up. Then we got some track and then the group wanted to have the ball roll down the track and when the ball roaled over the LED the LED wouled light up, it took a wile to figure the track out but eventually we figured it out. We also had a bucket os water, we were going to put dry ice in it so I hooked up red LEDs to make the fog glow red.

I learned alot more about electrical curcuts and wires. The LED light is a new thing to me and I think I've got it, I learned that on e side of the LED is longer than the other, so a certan side of the badary must match the LED. I also learned that to mutch voltage can burn out the LED light, so I must be very carefull about the voltage of the badary. Another thing I learned was that resisters slow down the electrical curent, but I also learned about electrical and arcatectural enganering, my grouup made a track and when the ball ran over the track the LED lights on the side lit up.

I learned that if you us scotch tape on an LED light there is a risk of a fire, you must use electrical tape. I learned about something called a bread board, it makes hooking up lots of wires easer. I also learned something on my own, there were someLED lights on a long cord kind of like Christmas lights, but there was an USB port on the end, so I
