Hi everyone.

for this homework I made a toy that doesn’t want to be touched. This is the early stage of a more complex idea where a toy can give you remote information from your house.

Since to do that require more time and knowledge, for now I connected a Sharp IR sensor to detect proximity connected with an LED and a speaker. at certain distance the puppet start complaining.

I found my father playing with him this morning in the kitchen.

// Uses a PIR sensor to detect movement, a speaker and an LED

int ledPin = 13; // choose the pin for the LED
int inputPin = 2; // choose the input pin (for PIR sensor)
int pirState = LOW; // we start, assuming no motion detected
int val = 0; // variable for reading the pin status
int pinSpeaker = 10; //Set up a speaker on a PWM pin (digital 9, 10, or 11)

void setup() {
pinMode(ledPin, OUTPUT); // declare LED as output
pinMode(inputPin, INPUT); // declare sensor as input
pinMode(pinSpeaker, OUTPUT);
Serial.begin(9600);
}

void loop(){
val = digitalRead(inputPin); // read input value
if (val == HIGH) { // check if the input is HIGH
digitalWrite(ledPin, HIGH); // turn LED ON
playTone(300, 160);
delay(0);
if (pirState == LOW) {
// we have just turned on
Serial.println(“Motion detected!”);
// We only want to print on the output change, not state
pirState = HIGH;

Serial.println(val);
}
} else {
digitalWrite(ledPin, LOW); // turn LED OFF
playTone(0, 0);
delay(300);
if (pirState == HIGH){
// we have just turned of
Serial.println(“Motion ended!”);
// We only want to print on the output change, not state
pirState = LOW;
}
}
}
// duration in mSecs, frequency in hertz
void playTone(long duration, int freq) {
duration *= 1000;
int period = (1.0 / freq) * 1000000;
long elapsed_time = 0;
while (elapsed_time < duration) {
digitalWrite(pinSpeaker,HIGH);
delayMicroseconds(period / 2);
digitalWrite(pinSpeaker, LOW);
delayMicroseconds(period / 2);
elapsed_time += (period);
}
}

It’s instrument box. When you move it, tilt it or press its sensor, the sound and RGB LED will change.

int piezo = 9;
int speaker = 9;
int sensor = A0;
int sensorValue = 0;
int sensorValue2 = 0;

int ledPin1 = 6;
int ledPin2 = 3;
int ledPin3 = 5;
int sensorPress = A5;

void setup() {
Serial.begin(9600);
pinMode(sensor, INPUT);
pinMode(sensorPress, INPUT);

pinMode(speaker,OUTPUT);
pinMode(ledPin1, OUTPUT);
pinMode(ledPin2, OUTPUT);
pinMode(ledPin3, OUTPUT);

}

void loop() {
sensorValue = analogRead(sensor);
Serial.println(sensorValue);
sensorValue2 = analogRead(sensorPress);
// Serial.println(sensorValue2);

analogWrite(ledPin1, sensorValue);
analogWrite(ledPin3, sensorValue2/2 + 50);
analogWrite(ledPin2, sensorValue2/2);

sensorValue = map(sensorValue,1,500,1000,4000);
tone(speaker,sensorValue);
// Serial.println(sensorValue);

}
