What We Did
We started learning the basics of circuits and the parts of them and eventually got to start doing some simple experiments. We plugged out RedBoard into our chrome books and ran the Arduino experiments that we were given. We set up the wires and then applied the code. We got to the point where we felt very comfortable with setting up the Arduino experiments and started to program our own codes for our Robot Art Show! For the Robot Art Show, my partner and I wanted to play the lyrics of I'm Yours by Jason Mraz on the LCD screen. The corresponding lights to the buttons would flash when that note should be played to tell the person to press that button. Resulting in I'm Yours being played.
Electromagnetic Lab Write Up
In this electromagnetic experiment I tested out how different voltages in batteries impact the magnetic field. I tested how many paper clips could be picked up with different voltages. The nail, wire, wraps of wire, and number of nails stayed the same for each experiment. We found out that the higher the voltage, the more paper clips picked up until 2.93V where it begins to decrease.
Content
Coulomb's Law
F = kq1q2/r^2
The force of attraction/repulsion between two static charges proportional to their charges and inverse to the square of the distance between them.
Circuits
Circuit - A complete loop made of conductive materials/elements going from one side of a power source to the other.
Series - Circuit with single path and multiple components, one after the other, all on the same path. The total resistance of resistors in a series is the sum of the series. This is when to resistors are next to each other.
Parallel - Circuit with branches each with separate paths for flow of charge/electrons. You can add the resistors in a series to get the total resistance. This is when the resistors are parallel from each other.
Ohm's Law
V=ir
Current - Flow of charge/electricity through the circuit. Measured in amperes (A).
Voltage - Potential energy different from one side of component to the other. Measured in volts (V).
Resistance - Amount of current is slowed or resisted through an obstacle. Measured in ohms (Ω).
Power - Rate of transferring electrical energy through a circuit. Measured in watts (W).
Programming and General Rules of Coding
With this project, I was completely new to programming and coding. With having no prior experience with it, I learned so much. I learned how to program my own code, set up a BreadBoard and RedBoard, and how to follow a code. I learned the order of how all code should go and how everything works.
Electromagnets
Electromagnets work by electricity from the battery going through the wire making the magnetic fields. The current from the battery goes through the wire from the positive side and back through the negative side of the battery. The right hand rule is to help us remember which way the current is going on the object. The fingers of the right hand show the direction of the magnetic field.
Reflection
I learned a lot about myself with this project. I learned that I enjoy setting up breadboards and coding a lot. Even though it was a challenge at the start because I was new to it all, I focused on learning it as much as I could. I did well with critical thinking and communicating. I thought through and focused on my work and I really feel like I improved my skills. I communicated my ideas, thoughts, and feelings. I think one thing I could work on more next project would be communicating. Although I feel like I expressed my thoughts well, I think I could have talked even more with my partner about our ideas. I also could improve my cooperation skills even more. I have been making extra efforts to hear other people opinions and combine our ideas.
