Real-World Analogies Clock's Second Hand Firefly Police Car Siren Turn Signal How It Works The pulse is a switch that opens and closes over and over again, sending a stream of short ON signals. When it's open, the signal from the...

How It Works The littleBits random Bit has 2 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,...

The remote trigger lets you use a common remote control with your Bit. Make your littleBits circuit and point a remote control at the remote trigger’s sensor. Then, press any button on your remote control to activate the Bit. The remote...

The sequencer allows you to connect up to 8 outputs and control them in sequential patterns. Sequences that would take as long as 4 days to program without littleBits will only take you seconds! HOW IT WORKS With the sequencer, you can...

The slide switch is a small and convenient way to turn your creations on and off. It uses a sturdy plastic lever to switch back and forth. Try it with any of your favorite Bits, like the DC motor or bright LED! Inventions With The Slide...

Real-World Analogies Clapper Ear How It Works The sound trigger has a microphone that measures how much noise is around it. When the noise gets to a certain level, the sound trigger will let the signal from the previous Bits through for...

Real-World Analogies Automatic Tea Kettle Thermometer Thermostat How It Works. The temperature sensor determines termperature via the IC that is located on top of the board. It communicates via I2C with an MCU located on the bottom of...

Think of the threshold as a toll booth. When the signal passing through a circuit reaches it, the threshold decides whether or not it can continue. Use it to make any sensor Bit (like a temperature sensor) into a trigger Bit! How It...

The timeout Bit is a settable timer. Try it after a button and follow it with a light. Press and release the button to start the countdown. How It Works In "on-off" mode, the light will go on as soon as you release the button...

The toggle switch Bit is a sturdy on-off switch that you can use to activate your creations with a nice, solid click. Try using it after a USB power Bit as an on-off switch for your whole creation. Inventions With The Toggle Switch Bit...

The littleBits Bluetooth Low Energy Bit (marked "BLE" on your Bit) is the easiest way to control your inventions wirelessly, from any smart device (like a phone or tablet). All you need is the littleBits Invent app and this Bit...

The branch Bit gives you more options for connecting your Bits: it lets you connect the output of a single Bit to as many as 3 others, oriented in different directions. Use it when you want to trigger light, sound and motion at the same...
