Circuit Diagram

Circuit

We started this project by doing different experiments with just circuits and components. Soon moving too, the blinky light test then we moved on to Arduino experiments with our Arduino uno kits. We took coding notes to go along with our experiments to note down important pieces of code to use later in the finial project.  We stepped back from Arduino experiments and wrote our electromagnet lab and then went back to doing coding experiments.  The coding experiments included using all of the different components in the kit separately and some of them together. Components that were used  are photo resisters, different types of LED'S,  a speaker, a motion sensor, servo motors, a temperature sensor, motors with wheels, and an LCD screen.

Once my partner and I finished the coding experiments we moved on to brainstorming possible actions to make our robot preform.  Originally, we wanted to have a " Night time sleeper" machine that would  blink cool calming colors with a LCD screen that would tell you 'goodnight!'  and play calming tones on the Buzzer but we decided not to do that because there was not enough room and seemed to simple to do.  Finally, we made up our mind and looked through the Arduino booklet with all the different circuits and picked out which circuits would make our finial idea come true. Our finial design is a starter on how to play Ode to Joy by Beethoven, it gave all the information to play Ode to Joy. It provided the artist full name, what notes are use on a c major scale, and an example of what it is suppose to sound like as an end result, and finally thanking you note for following along. 

Content

Coulombs Law-The force of attraction/repulsion between two static charges is proportional to their charges and inverse to the square of distance between them. F=kq1q2/d^2, k=9x10^9 Nm^2/C^2.

Charge-Magnitude of electrical quantity. C=6.24x10^18 electrons. 

Ohm's Law-V=ir. Voltage equals current times resistance. 

Kirchhoff's Current Law-The sum of the currents going into a connection must equal the sum of the currents leaving the connection.

Kirchhoff's Voltage Law-The sum of the voltages around a circuit must be equal to zero.

Circuit-A closed loop of conductive material from one side of a power source to the other(+ to -).

Parallel circuit-A circuit with branches, each with a separate path for flow of charge.

Series circuit-A circuit with a single path and multiple components, one after another all on the same path.

Current(In parallel and in series)-Amount of change of electricity through a circuit. Measured in Amps, with the variable i, and measured with an ammeter. Current stays the same in a series circuit and splits in a parallel circuit.

Voltage(In parallel and in series)-Potential energy difference from one side of a component to the other side. Measured in volts, with the variable V, and measured with a voltmeter. Voltage splits in a series circuit and stays the same in a parallel circuit

Resistance-The amount current is slowed, or resisted, through an obstacle. Measured in Ohms(Ω), variable r. In a series circuit, the total resistance is equal to the sum of the resistors. In a parallel circuit, the sum of the inverse of the resistors equals the inverse of the total resistance.

Power-Rate of transferring energy through a circuit. The variable is P, and it is measured in watts, or Joules per second.

Electromagnetism- The interaction of electric currents in fields to create a magnetic field.

 Reflection: 

Overall, this project I feel that I exceeded at empathy and critical thinking for this project with my partner. I found new solutions to many of the problems that my partner and I faced, and asked for helped when it was very much needed.  During the stage of the project where we were experimenting with circuits and Arduino, my partner and I ran into some trouble for some of the circuits but was quickly solved by looking back at the Arduino booklet and analyze/comparing it with our circuit board. My partner took care of constructing the circuit and I was in charge of our code.  Empathy I feel was exucuded well during this project. Since my partner was under the weather and had to miss a few days I didn't let it hold us back and kept moving forward with the experiments and writing down codes so it would be easier for both of us. I was there when my partner needed help even when I was doing my own thing. 

Even though we worked well together and finished what we started with a well score I feel like I could have improvement on collaborating and conscientious learning. Looking back I wish I could improve my collaborating and be more involved in wiring the  Arduino experiments and our robot as well. Though I did do work I could have been less separated from my partner.  Conscientious learning is also something I felt that I could have done better and push myself more at. Seeing my mistakes and noticing them but not having enough effort to stop them from happening. I did not reflect enough so the same mistake kept popping up. Lastly, this was a great experience and It showcased my mistakes but also my achievements.
