Yes! We can build electronics projects just as easy as piling bricks. The Arduino/Freeduino movement has made programming and physical computing easier than ever. The Electronic Brick system simplifies the process of interfacing sensors, inputs/outputs, and other various electronic components greatly!
By using Electronic Bricks, you can connect Arduino compatible boards easily with various digital, analog, and I2C/Uart interfaces. These breadboard-less, firm connections are compatible with an extensive list of modules such as potentiometers, sensors, relays, servos, buttons, and much more! Just plug and play!
Each sensor or I/O module has a buckled 3 pin plug with VCC, GND and Output, which has a corresponding port on the sensor interface brick shield modules. Buckled brick cables are like cement for bricks, make the connections easier, secure, and more professional looking.
