This is to show what wires I connected to where, to also show what my final product was at the end.

Code:

*/int speakerPin = 10; //the pin that buzzer is connected to
#include <LiquidCrystal.h> //the liquid crystal library contains commands for printing to the display
LiquidCrystal lcd(13, 12, 11, 10, 9, 8); // tell the RedBoard what pins are connected to the display
void setup(){ lcd.begin(16, 2); //tell the lcd library that we are using a display that is 16 characters wide and 2 characters high lcd.clear(); //clear the display pinMode(speakerPin, OUTPUT); //set the output pin for the speaker}
void loop(){ lcd.setCursor(0, 0); //set the cursor to the 0,0 position (top left corner) lcd.print("-the temptations"); //print -the temptations! starting at that position
lcd.setCursor(0, 1); //move the cursor to the first space of the bottom row lcd.print(millis() / 1000); //print the number of seconds that have passed since the last reset

Circuits, Electronics experiments, and Programming

During this unit we focused on using the website tinkercad. This allowed us to be able to do simulations of using a breadboard and coding. We could experiment with using Arduino Programming and make our own code. This taught us how to use buzzers, buttons, screens, and LED lights. During the beginning of this unit we focused a lot on lighting up an LED light uthingssing a resistor, potentiometer, and other tools. Shortly after taking our Blinky Light Quiz we headed straight into ournext part of the unit. We started next doing experiments, this led us to our programming quiz. This quiz consisted of us using tinkercad to make an LED blink on and off, then explainging the code. I think our last part of this unit was my favorite though. We used tinkercad and our prior knowlege of coding. I decided to make the buzzer on the breadboard play to the sound of the song "Brown Eyed Girl"by The Temptations. I also added an LCD screen that displayed the words "-The Teptations". I personally really enjoyed this project despite the few set-backs I had. I liked this onebecause there were so many options of what you could do.

Electromegnetic Lab Writeup

The difference in a voltage change does not affect whether the magnet becomes stronger. Testing the magnitude I changed the battery to ones of a different size and voltage. In the table it states how even with a lower change in voltage from double A battery to a C battery they both picked up the same amount of safety pins. This leads us to believe that the difference in voltage has nothing to do with the magnitude of this magnet. In the chart it shows us again how the voltage doesn’t change the power of the magnet. In the end changing the batteries to higher or lower voltage won’t have much of a difference on the magnitude.
