The littleBits split module sends a single input to two wired outputs. It's great for connecting one output to two inputs, like using a keyboard to control two oscillators. But keep in mind that it can be used just like a wire module if you ignore one of its outputs.

The littleBits random module has two modes: "noise" and "random voltage". In "noise" mode, it outputs white noise, like a television set not tuned to any channel. In "random voltage" mode, it outputs random voltage signals that can control oscillators and make them play random pitches. Use the "trigger out" connector and "speed" dial of the micro sequencer to set the timing of the random output pulses and use an input Bits module like a dimmer to control the range of your random outputs.

The littleBits light sensor measures how much light is shining on it. It has two modes: “light” and “dark”. In “light” mode, the more light shines on the sensor, the higher the signal it sends out. In “dark” mode, it's just the opposite – the signal increases the darker it gets. You can use a screwdriver to adjust the sensitivity. Use a bargraph to see how it's working!

Learn to paint with light, make your own "Operation Game," sew interactive stuffed creatures, build "Rube Goldberg" machines, design artbots, produce mathematically generated mosaic tiles, program adventure games, and more! Your MaKey MaKey, LEGO, old computer, recycled junk, and 3D printer will be put to good use in these fun and educational projects. With The Invent To Learn Guide to Fun in hand, kids, parents, and teachers are invited to embark on an exciting and fun learning adventure!

The buzzer Bit is just what it sounds like: it makes a noise that you just can't ignore. It buzzes whenever it gets an ON signal. Try using it to make your own doorbell or alarm!

The sound trigger listens to the noise level in your room, and sends an ON signal when it gets over a certain level. You can make that threshold louder or softer using the included screwdriver. We like to use it with an LED to light up your room when you snap your fingers. The sound trigger features an electret microphone that triggers a 5V output when the set threshold is reached. The output of the module will remain high for 3 seconds. If the input signal is high, the module functionality is enabled. If the input signal is low, the module function is disabled.

If there is a littleBits module that doesn’t exist, you now have the power to make it. The proto module is what littleBits engineers use to build and prototype new modules. Hack into existing modules or invent a brand new one by connecting to printed circuit boards or solderless breadboards. With the proto module, you have direct access to power, ground and signal lines needed to take measurements and connect to other instruments.

The Branch Bit gives you more options for connecting your littleBits: it lets you connect the output of a single Bit to as many as three others, oriented in different directions. Use it when you want to trigger light, sound and motion at the same time.

The vibration motor is very similar to the device that makes your cellphone shake when you get a text. With this module, you can make anything vibrate and buzz! This module also includes the vibeSnap-- an accessory that helps you attach stuff - like paper, tin foil, or a pipecleaner - to the motor.

The bargraph is one of littleBits favourite Bits: The bargraph shows you how much signal the Bit is receiving with a display of 5 light-emitting diodes (LEDs) in different colours. Try it with a pressure sensor to make your own strength-o-meter.

When used with DC motors, this pair of wheels is perfect for making bots, cars, and all sorts of spinning inventions. These wheels work with cross axle DC motors.

The remote trigger lets you use a common remote control with your modules. Make your littleBits circuit and point your remote control at the remote trigger’s sensor. Then, press any button on your remote control to activate the module. The remote trigger will work with almost any button on a remote that uses infrared light to send signals.

The pulse Bit is like an electronic heartbeat. It sends out a stream of short ON signals, and you can make the speed of the pulses faster or slower using the included screwdriver. It's great for making LEDs blink!

The fork Bit gives you more options for connecting your Bits: it lets you connect the output of a single Bit to as many as three others. The additional Bits will be right next to each other. Use it when you want to trigger light, sound, and motion at the same time.

The USB power may be the smallest in the series, but it's big enough to send juice to all your creations. Connect a USB cable (included) to your computer or phone charger to start the power flowing. Try it with an LED to make the simplest littleBits circuit. If you're looking for a permanent installation, the USB power adapter enables you to plug your USB power directly into the wall. Using a USB connection to a computer, you have access to 500mA of power for your circuit. When using the USB Wall Adapter, you should have up to 1A of power available. The red LED shows you when the module is powered. Note: The USB power Bit does not provide a data connection.
