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 Hunt Sensor is a sensor based on TCRT5000 photoelectric sensitive element.It can sensitively detect the infrared reflected signal. Together with Arduino specific sensor shield, Hunt Sensor can be widely used in many fields, ranging from performing black and white line detection, obstacle detection , to shredding detection for fax machine or paper shredder, meter pulse data sampling and other related works Adjustable sensitivity (shown in blue digital potentiometer adjustment). Three pins electronic building blocks interface: input 5V - GND. S pin output digital voltage signal 0-1 Operating voltage: DC 5.0V

Quick Start
Hardware Connection
Connection note: Connect this module to the P1 port on OCTOPUS:BIT.
Programming
Code
Results
Put this module 9mm away from the black plane, the "icon" pattern can be seen on micro:bit; 9mm away from the white plane, the "square" pattern can be seen on the micro:bit. The height can be adjusted by the sensitivity regulation controlled by the potentiometer.

Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- 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.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
- 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.
- Shield
- An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
- 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.
- VCC
- VCC is the positive power-supply connection on a chip or module. Connecting it to the correct supply voltage is needed for the part to power on and helps avoid damaging the electronics.
