Overview Microphone based sound sensor can be connected to the analog I/O port, the analog value will be changed whenever sound is detected. A sound recorder can be made by reading and saving the analog value. DESCRIPTION What is an electronic brick? An electronic brick is an electronic module which can be assembled like Lego bricks simply by plugging in and pulling out. Compared to traditional universal boards and circuit modules assembled with various electronic components, electronic brick has standardized interfaces, plug and play, simplifying construction of prototype circuit on one’s own. There are many types of electronic bricks, and we provide more than twenty types with different functions including buttons, sensors, Bluetooth modules, etc, whose functions cover from sensor to motor drive, from Ethernet to wireless communication via Bluetooth, and so on. We will continue to add more types to meet the various needs of different projects. Electronic brick of microphone can be connected to the analog I / O port, when speaking to the microphone, the analog value will be changed. A recorder can be made by reading and saving the analog value. Features 1. Plug and Play, easy to use.Compatible with the mainstream 2.54 interfaces and 4-Pin Grove interfaces in the market. 2. With use of M4 standard fixed holes, compatible with M4-standard kits such as Lego and Makeblock Specifications PCB Size 33.0mm X 14.0mm X 1.6mm Working voltage 5V DC Operating voltage 5V DC Compatible interfaces 2.54 3-pin interface and 4-pin Grove interface(1) Note 1: S for digital output port , V and G for voltage at the common collector and ground respectively Electrical characteristics Parameter Min. Typical Max. Unit Working voltage 4.5 5 5.5 VDC Digital output voltage (VCC=5V) 0 - 5 V Working current (VCC=5V) - 260 - uA Frequency range 100 - 10000 Hz Sensitivity - -50 - dB Demo Code Connect S port of electronic brick of microphone to A0 port of Arduino, and we will use the following program to read the analog value. When the value exceeds the threshold, the LED indicator will flash. const int ledPin = 13; // the number of the LED pin const int thresholdvalue=400; //The threshold to turn the led on void setup() { pinMode(ledPin, OUTPUT); } void loop() { int sensorValue = analogRead(A0); //use A0 to read the electrical signal if(sensorValue>thresholdvalue) digitalWrite(ledPin,HIGH); //if the value read from A0 is larger than 400,then light the LED delay(200); digitalWrite(ledPin,LOW); } Specification Brick Type Sensor Brick Brick Interface 3PIN Brick Power Supply 5V Board Size 33 x 14 x 1.6mm LED Color No Weight 15.00g Model IM120710013 Download Schematic SCH_IM120710013 Datasheet DS_IM120710013 Demo Code DEMO_IM120710013
