TED Talk Notes
1) https://www.hackster.io/pix3lot/pac-man-led-pixel-panel-costume-515666 - a family made like up pac man costumes by using arduino - the costumes were made with a laser cutter and then LED lights were covered on the outlines of the pac man characters and programmed in arduino to change faces 2) https://www.hackster.io/Frogger1108/homemade-arduino-pinball-machine-4a3314 - this person created a homemade pinball machine - they bought a pinball skeleton and then created the machine themselves using Arduino 3) https://www.hackster.io/iotboys/control-led-using-your-voice-command-b396df - here a person created voice controlling LED lights - they used Arduino in the building of the breadboard and with bluetooth allowed a voice to activate the lights turning on and off

Creating this synthesizer was perfect for gaining more knowledge on different components. We used resistors and capacitors of different ranges. For example one potentiometer was 1M while another was 5k. In addition we used a 556 chip, speaker, and battery. I used the document given with the synthesizer directions to create my circuit. The guide helped my process run smoothly and the soldering was easy because we had learned how to use the solder beforehand. In the pictures you can see different stages of the creation of my circuit. Currently, I am troubleshooting my synthesizer because it is not emitting a sound. I just soldered one wire of my speaker so it can go into the positive rail more easily because beforehand the wire was very weak. To begin this synthesizer we grabbed all of our needed materials shown in the picture. Next I took out all the materials and laid them onto a piece of white paper where I labeled each part. From my teardown and after learning about classmates' teardowns I understood each part. As seen in the picture: There are four resistors, two 1M, and the others 5k and1k. In general, resistors control the amount of energy that can flow. Three capacitors of 0.01uF, 0.1uF and 10uF. Overall, capacitors are used to store charge and smooth out circuits. The other parts are a wire, a speaker, a switch (to turn the synthesizer on and off) and the breadboard (used to assemble the circuit). And the 556 chip has two timers in it that control oscillation and vibration. Schematics
