PROGRAMMING
Physics Concepts:
Circuit: a complete loop of conductive material with a power source
Resistors: poor conductors that reduce voltage (ex: light bulbs)
Voltage: power that electricity gives off, push/pull of electricity, pressure or Potential Energy difference
Series circuits: draws less electricity because each additional bulb is extra resistance. Voltage changes, but current remains the same throughout.
Parallel circuits: draws more electricity because as the number of bulbs increases, the resistance in turn goes down. Parallel circuits are independent, unless they're in series with another set of parallel circuits.
Kirchoff's 1st Rule: "The total current out of a node equals the total current into the node."
Breadboards: vertical rows are connected in the outermost columns on both the left and right side; in the center columns, horizontal rows are connected
Ohm's Law: Voltage = Current x Resistance

Resistors are banded with different colors to indicate the strength of the resistor. The code goes as follows...

what is a resistor?
A resistor is anything that electricity can not travel through easily. When electricity is forced through a resistor, often the energy in the electricity is changed into another form of energy, such as light or heat. The reason a light bulb glows is that electricity is forced through tungsten, which is a resistor. The energy is released as light and heat.
what we had to do...
For the this project we had to program a bread board to make robotic art with flashing lights and music. When i was assigned this project I had no clue how i was going to do it because I didn't even know what programming was. With a lot of help from my teachers and classmates I was able to at least understand what i was supposed to be doing. For our song we made the buzzer to play row your boat.

I am not going to lie, at first I had no idea what I was doing at all. When we were given the packet of mini experiments to do using the breadboards, the first thing that went through my mind was that I couldn't do it. While doing many of these experiments, Katie and I had to continuously ask Mrs. Havel and our classmates for help. It was extremely easy to get everything jumbled up into an inscrutable mess, so it really reinforced the idea of neat organization. Along with the programming, this unit took a lot of will to stay focused and on-task for me, I do not seem to find electricity naturally intriguing but in the end, it helped me learn that although what is being taught seem asinine and boring, it proves to harbor invaluable resources for future reference. Anything is worth learning; you never know when you may need it! This project was extremely educational, really. I hardly knew a thing about electricity; I knew what it was, what it can and does do, and why it does it, but I never understood the way electricity does the things it does, and now I can manipulate it do do things I want. Along with coding, this was just a really helpful project.
