S3238806 4B's Project
From Physical Programming
For the 4B's project, i wanted to make a device that will notify the parent if the child was at a certain distant away from the parent. Making a toy that transformed into a bag for the child to carry and a bag for the parent to carry the device.
In doing so we used an Arduino with a Magnetic sensor and a piezo buzzer. When the magnet is out of a specified value a set melody will be set off and will keep repeating itself until the magnet is within range again.

A Preview of the code is shown below:
- include "pitches.h"
int melody[] = {
NOTE_G4, NOTE_A4, NOTE_B4, NOTE_G4, NOTE_A4, NOTE_B4, NOTE_G4, NOTE_G4, NOTE_G4,NOTE_G4, NOTE_A4, NOTE_A4, NOTE_A4, NOTE_A4, NOTE_G4, NOTE_A4, NOTE_B4};
int sensorPin = 0;
int trigVal = 100;
int meanVal;
int speakerPin = 8;
int timeDelay = 10; /
int noteDurations[] = {
4, 4, 2, 4, 4, 2, 8, 8, 8, 8, 8, 8, 8, 8, 4, 4, 2 };
void setup() {
meanVal = analogRead(sensorPin); Serial.begin(9600); Serial.println(meanVal); delay(100);
}
void loop() {
int currentVal = analogRead(sensorPin);
int diff = abs(meanVal - currentVal);
Serial.println(diff);
if(diff > trigVal) {
for (int thisNote = 0; thisNote < 8; thisNote++) {
int noteDuration = 1000/noteDurations[thisNote];
tone(speakerPin, melody[thisNote],noteDuration);
int pauseBetweenNotes = noteDuration * 2;
delay(timeDelay);
}
}
}
Thank you for all the help Scott! =D
