Octopus Electronic Bricks you can use them 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; This is a simple infrared receiver sensorand mainly receive infrared signal through HS0038 infrared diode. HS0038 is particularly sensitive to the infrared signaland it can receive the infrared signal very swiftly. It can be used in infrared remote control infrared transmitter works. 3P buckled wires connector; Easy to plug and play; Able to achieve very interesting and an interactive work
