Robot Art Show

Overview of Project:

In this project, we were tasked with building a circuit that demonstrated our knowledge of coding and electricity. First, we learned the different types of circuits and their features. We conducted experiments to figure out the relationship between voltage, resistance, and current. We worked through a series of tests and problems using the Tinkercad simulation, before moving on to our final project. We came up with several ideas, before eventually settling on a instructional piano game. Our project was composed of an LCD screen to introduce the song and direct the player with certain notes to play, 3 buttons acting as keys/notes, LED lights that flashed when their corresponding button was pressed, and a buzzer that played our notes to create our song. In the end, we were able to code the game to play 2 songs: Mary Had A Little Lamb, & Hot Cross Buns.

Sophia & Nora's Piano Game Code

This was our final code, complete with color-coded explanations of each step.

This was our final product for our instructional piano game. We ended up running to an issue where we ran out of pins on a single Arduino, so we had to move the LCD screen and one of the buttons to another Arduino. This brought even more issues because it was difficult to run the two codes at the same time and have everything go smoothly.

Robot Art Show: Circuit Diagram

Our final circuit ended up looking extremely complex, so to simplify it when explaining we we created a clear circuit diagram. We labeled the two Arduinos and their roles, and organized our circuit so it was clear where each portion was attached to.

Nora Schiltgen - Electromagnet Lab

This was one of the first experiments we did to be introduced to current and voltage. We had to choose an aspect to change and then find how the voltage was affected using a series of experiments.

Content

Coulomb's Law

Coulomb's law is a law that states that the force of attraction and repulsion between 2 charges is proportional to their charges & inverse to the square of the distance between them. It is represented by the equation, f= kq1q2/d^2.

Circuit

A circuit is a complete loop of conductive material from 1 side of a power source to the other, or the positive side to the negative side.

Series Circuit

A series circuit is a type of circuit that has a single path and multiple components lined up one after another. The resistance of a series circuit is modeled by the equation r1+r2+r3=r, where r is the resistance of each component.

Parallel Circuit

A parallel circuit is another type of circuit in which there are several pathways for the electricity to flow through. The resistance of a parallel circuit is represented by the equation 1/r1+1/r2+1/r3=1/r

Resistance

The resistance is the amount of current that is slowed down or resisted through a certain component, like a resistor. It is measured in ohms.

Voltage

Voltage is the potential energy difference from one side of a component to another side. It is measured in volts.

Current

The current is the flow of the charge or electricity through the circuit. The current is measured in Amps. The voltage, resistance, and current have a relationship that is modeled by the formula v=ir.

Reflection

In this project, I was very proud of the knowledge I was able to retain. Both my partner and I didn't have a lot of experience in coding or circuits, so we were both eager to learn as much as possible to understand what we were creating. Something I did very well in this project was time management. This was pleasantly surprising, because it has typically been something my past groups have struggled with. I was able to work efficiently with my partner to learn the material, while also ensuring that we were still understanding the material without rushing it. We actually ended up finishing our original idea early, which gave us plenty of time to revise our design and improve it. Another thing I did well in this project was collaboration. My partner and I were both pretty good at communicating our ideas with each other, and we were comfortable with sharing our opinions. We developed an efficient system that allowed us to go at a faster pace while also retaining all the necessary and valuable information. We both completed the project to the best of our ability. The main thing I needed to work on in this project was leadership. My partner took a leadership role pretty quickly in our project, and I was at first overwhelmed by the unfamiliarity of the material we were learning, so I took a step back from being a leader. I think if I took a more active role in suggesting ideas to improve our build, it could definitely have benefited us in some way. I was able to become more engaged leadership wise throughout our project, and I always put all my effort into working on it.
