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. Octopus Tilt Sensor is a sensor based on tilt switchused together with Arduino specific sensor shield for the measurement of object angle.
