B2B Lab: LEGO & litttleBits Together..(Updated)

LEGO® and littleBits®, as two modular building systems they are awesome together. Some of the Brics~2~Bots engineers started working on projects that use LEGO elements with littleBits to learn electronics. 

We started off with a simple Power + Fan (output) to cool things off.

Luc added a button to control the fan: Power + Button (input) + fan (output).

We also made Telegraph devices. First we research telegraphs and the Morse Code on the Internet and printed out the code. 

In 1836, Samuel Morse, American inventor and painter, American physicist Joseph Henry and Alfred Vail created the single wire telegraph system to transmit information for long distances via radio waves. A coded system which became known as the Morse Code, sent as a series of electrical signals - short signals represented as dots and long signals are referred as dashes. Letters and numbers were assigned a combination of dots and/or dashes.The International Morse Code has been in use for more than 160 years longer than any other electrical coding system. The Morse Code was  use in aviation, amateur radio, the general public, and military personnel in the US Navy. The most common message is SOS and in Morse Code (… - - - …). It is rarely used today, because of cell phone and Internet communication, but it is still pretty cool.

Brandon’s telegraph includes a Buzzer and LED to make  the Morse Code signals. Power + Button (input) + Buzzer (output) + Long LED (output).

Spooky Box

Luc's Spooky Box Surprise includes Power + Sound sensor (input) + Pulse (input) + Split (wire) + 2 Bright LED (output).
The Sound sensor picks up the sound of someone entering a room (it is adjustable to sensitivity) causing the LEDs to flash (Pulse). You can make it an alarm by adding a Buzzer.

Olivia made a Night Light that responds to sound.

It has Power + Toggle Switch (input) + Sound sensor (input) + Slider (input) + Wire + Bright LED (output).
