Output Bits (Lights and Sound)
These are the bits that output something, whether it be a light, some type of signal, a sound, or something else.
These bits actually do the work, as with just input and logic bits, nothing will happen, so you need an output bit for your device to function.
All of these bits also pass electricity along, so connecting another bit to the end of an output will continue your device. This means you can have as many buzzers, speakers, and other noise making bits as you want! (Though we advise against this.)
This section is all about the bits that produce lights and sound
Buzzer
This bit creates a buzzing sound when recieving power. It's very simple as it can't be controlled too much and has a very simple use.
Other Info
- You can use the dimmer or slide dimmer bits to control the volume of the buzz.
Speaker
The speaker bit, also known as the synth speaker, produces sound when given an input from a sound producing bit
How to Use
The speaker bit doesn't just produce sound when given power, it requires an input bit to know what sound to produce.
Instructions:
- Connect a sound producing input bit to the power bit. (ex. oscillator, MP3 Player, keyboard)
- Connect the speaker to the input bit.
- Tune the input bit and the speaker's volume as needed, then turn on the power and the synth speaker will start playing the tune.
LED
This bit will light up green when it recieves power.
Other Info
- You can use the dimmer or slide dimmer bits to control the intensity of the LED bits.
- The light sensor bit can be activated by any bit that produces light, including all LED bits.
Long LED
This bit is almost exactly the same as the normal LED bit, but has a few key differences.
Those differences are:
- Outputs a bluish-white light instead of a bright green one.
- As seen in the picture above, the LED is extended from the main electronic by a wire.
Bright LED
The Bright LED is exactly the same as the normal LED bit, but is much brighter and is colored white instead of green.
UV LED
The UV LED is the same as the long LED bit, though it emits ultraviolet (UV) light instead of normal, visible light.
IR LED
The IR LED follows the same pattern as the UV LED and long LED bits, but emits infrared (IR) light instead of UV or visible light.
Other Info
- Because it emits IR light, it can be used to activate the remote trigger bit.
RGB LED
The RGB LED uses three dials (slides on some models) to control three values (red, green, and blue), to reach the entire spectrum of visible color.
How to Use
As you can see in the picture, the RGB LED bit has three dials that can be turned with the purple littleBits screwdriver. Adjusting these dials will control the amount of red, green, and blue that the LED outputs.
NOTE: Some newer models, like the one pictured on the littleBits website have slides instead of screwdriver dials, which makes adjusting the values much easier. These newer models work no different than the original ones, and the way you control the values is the only thing that has changed.
