Octopus Electronic Bricks, you can use them to build electronics projects just as easy as piling bricks. By using Octopus electronic bricks, you may connect Arduino/Freaduino compatible boards easily with various digital, analog and I2C/Uart interfaces. These the breadboard-less firm connection are prepared to extensive modules like poteniometers, sensors, relays, servos…even buttons, just plug and play.
OCTOPUS Sound Sensor is a sensor module based on MIC sound sensing element . Sound Sensor is particularly sensitive to sound intensity,and it can be used to detect ambient sound level, but it can not identify the size of sound and the specific sound frequencies. It is available to make voice switches and other works.
3 pins electronic building block interface: input5V - GND, S for detection pin
Parameter:
Operating voltage:
Adjustable sensitivity (shown in blue digital potentiometer adjustment)
With signal LED (if the signal output, the LED will be on)
Output type: Digital switching output 0-1(If detect sound,output “1”, and the signal LED will be on )

Jargon buster
Plain-language definitions for the technical terms used above.
- GND
- GND is the ground or reference connection (0 V) for a circuit. When connecting two devices together, their grounds must be joined so both agree on what counts as a low or high signal.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- potentiometer
- A variable resistor usually turned with a knob or shaft to create an adjustable electrical signal. It is often used for inputs such as volume, brightness or position, so it helps beginners learn how a microcontroller reads changing values.
- UART
- UART is a simple asynchronous serial interface that sends data over separate transmit and receive wires, usually labelled TX and RX, with both ends set to the same baud rate. It is a common way for microcontrollers and other serial devices to exchange data.
