Final Project SOMBRERO: Is up and running and putting the hat together was the way I kind of planned it would look like; however it was not easy as looks
Function: A button would be pressed and 3 other switches and gears would be activate which is the buzzer piezo playing the French Can Can, the continuous servo which is rotating a small car with a magnet that will hit 3 magnetic reed switches. These would light up the 7 LED. Then flipping the switch would shut the whole thing off all together.
Where it would be used: Parties, school on crazy hat day, or it could be part of a Halloween costume.
Here we got me hooking up the 7 LED lights in Parallel.
Getting this hooked up to the hat is no easy method as it involved for me tape and sewing that tap onto the hat. The reason I had to put this wire configuration on the baseball hat was to allow the user to wear the hat without the feeling of wires. As the sombrero is a bit high enough to allow them in
This hat needed a stable train track to hold the lego car with the magnet in the air. The magnet reeds are sticking out on the sides as they are attracted to the magnet on the Lego car. The buzzer will be playing the French can can which all functions of the rotating servo to the magnetic reeds and the Song the French Can Can are activated by a button that the user will hold.
The hat’s problem was the car, and the train tracks weren’t securely fasted onto the hat. So I gluegunned the train track to the hat. Then measured some wire strung to one of the legs on the servo. Get a sturdy wire and string it.
This is the my code for my final project:
#include <Servo.h>
// constants won’t change. They’re used here to
// set pin numbers:
const int buttonPin = 10;// the number of the pushbutton pin
const int ledPin = 5; // the number of the LED pin
Servo myservo; // create servo object to control a servo
// a maximum of eight servo objects can be created
int pos = 0; // variable to store the servo position
const int magbuttonPin = 2;// the number of the pushbutton pin
const int magbuttonPin2 = 12;
const int magbuttonPin3 = 8;
const int magledPin = 13; // the number of the LED pin
// variables will change:
int magbuttonState = 0; // variable for reading the pushbutton status
int magbuttonState2 = 0;
int magbuttonState3 = 0;
// variables will change:
