About
This project uses the Microphone to detect clapping noises and turns on or off the LED if it senses two claps with a second pause inbetween. This project was designed for the second generation mCookie Maker kits (102 Basic, 202 Advanced and 302 Expert kits).
Required Materials
For 102 Basic Kit
- 1 x mCookie Core
- 1 x mCookie USB TTL
- 1 x mCookie Sensor Hub
- 1 x Single ColorLED
- 1 x Microphone Sensor
- 1 x Buzzer
- 3 x Sensor Cable
- 1 x MicroUSB Cable
Build
- Connect the Single ColorLED to the Sensor Hub on Pin A0/A1
- Connect the Buzzer to the Sensor Hub on Pin 6/7
- Connect the Microphone to the Sensor Hub on Pin A2/A3
- Grab the mCookie USBTTL and Stack the mCookie Core on top.
- Stack the mCookie Sensor on top of that.
- Plug in the MicroUSB cable to the mCookie USBTTL a computer.
Program
Copy and paste the code below and upload.
#include <Adafruit_NeoPixel.h> //Import the library for the ColorLED.
#include <stdint.h>
#define MIC_PIN A2
#define BUZZER_PIN 6
#define LED_PIN A0
//The minimum amount of clap loudness to be registered as a clap
const uint16_t CLAP_LOUDNESS_THRESHOLD = 400;
//The maximum loudness between the two claps
const uint16_t SLIENT_LOUDNESS_THRESHOLD = 200;
volatile uint16_t mic_value;
unsigned long second_clap_timer;
bool leds_are_on = false;
void setup() {
pinMode(LED_PIN, OUTPUT);
Serial.begin(9600);
// put your setup code here, to run once:
pinMode(MIC_PIN, INPUT);
pinMode(BUZZER_PIN, OUTPUT);
}
void loop() {
// put your main code here, to run repeatedly:
//Take in mic reading for the first clap
uint16_t mic_value = analogRead(MIC_PIN);
//Check if it is greater than the threadhold
if ( mic_value > CLAP_LOUDNESS_THRESHOLD ) {
Serial.println("First clap detected!");
delay(1000); //Wait 500 milliseconds
//Read in a new mic value for the silence between the claps
mic_value = analogRead(mic_value);
Serial.println(mic_value);
//If the value is under the threshold, then it is slient
if ( mic_value < SLIENT_LOUDNESS_THRESHOLD ) {
Serial.println("Slience detected!");
//wait a bit of time beforce looking for the second clap
delay(1000);
second_clap_timer = millis();
while(((millis() - second_clap_timer) < 2000)){
mic_value = analogRead(MIC_PIN);
if(mic_value > CLAP_LOUDNESS_THRESHOLD){
Serial.println("Second clap detected!");
tone(BUZZER_PIN, 3038, 200);
if( leds_are_on == false ){
activate_light();
}
else{
deactivate_light();
}
delay(1000);
break;
}
}
}
}
delay(1);
}
void activate_light() {
digitalWrite(LED_PIN, HIGH);
leds_are_on = true;
}
void deactivate_light() {
digitalWrite(LED_PIN, LOW);
leds_are_on = false;
return;
}Usage
Clap once, wait about 1-2 seconds, then clap another time. The LED should turn on. Repeating the sequence will turn off the LED.
