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
- 1 x mCookie Core
- 1 x mCookie USB TTL (102 Kit) or 1 x mBattery (202/302 Kit)
- 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
NOTE: When connecting sensor wires, push on the plastic connector and not on the wires. Pushing on the wire can damage them.
- 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 or mBattery and Stack the mCookie Core on top.
- Stack the mCookie Sensor on top of that.
- Plug in the MicroUSB cable to the mCookie USBTTL or mBattery to a computer.
Program
1. Connect mCookie Core to the PC with the USB Cable. Open the Microduino IDE.
2. Download the project file and unzip: File:Clap Light X02.zip.
- Using the Microduino IDE and go to File > Open... and navigate to the unzipped folder. Open the Clap_Light_X02.ino file.
3. Select the board, processor and port:
- Go to Tools > Board and select Microduino/mCookie-Core (328p)
- Go to Tools > Processor and select Atmega328P16M,5V
- Go to Tools > Port and select the available port
4. Upload the program by clicking on the right arrow icon on the top left of the window. Or under Sketch > Upload.
NOTE: If not using the default Core module included in the kits, please follow the selecting the board and processor guide.
Debugging
- Open the Serial monitor. Information will print out when the first clap is detected as "First clap detected!".
- Then a value will print out which is the silent value. If it is under the threshold, "Silence detected!" will print.
- "Second clap detected!" will print if it detected a second clap.
Tweaking
Variables can be edited to change the threshold / detection value for various functions to better fine tune to your environment.
DEBUG un-comment to debug.
MIC_PIN defines the pin that connects to the Microphone.
BUZZER_PIN defines the pin that connects to the Buzzer.
LED_PIN defines the pin that connects to the LED.
CLAP_LOUDNESS_THRESHOLD will change the clapping loudness trigger point. Lower values means a weaker noise level is detected as a clap.
- Adjustable between 0 ~ 1023
- Default is 400
SILENT_LOUDNESS_THRESHOLD will change the silent registry level. Higher values will mean that higher noise levels will be registered as a silence.
- Adjustable between 0 ~ 1023
- Default is 200
PAUSE_TIME will change the time in which you are required to pause between claps in milliseconds. Lower values will detect faster claps, but there is settling time on the Microphone, which means too short of a pause time won't be detectable as silence.
- Default is 200 milliseconds (1/5 of a second)
Usage
Clap once, wait about 1 second, then clap another time. The LED should turn on and a beep noise will occur. Repeating the sequence will turn off the LED.
