Hands-On STEAM Making & Tinkering Kits for Classrooms & Creators

The littleBits proximity sensor detects objects in front of it and can tell whether something is near or far — a great starting point for automation and robotics projects. Combine it with other input Bits to build responsive inventions. Try it: use it to make a self-navigating vehicle that avoids obstacles, or a hands-free instrument you play by waving.

The littleBits servo is a controllable motor that can swing back and forth or turn to a set position, giving students precise, repeatable movement in their builds. Its cross-axle shaft fits any littleBits accessory with a cross-axle opening, and it works alongside our other output Bits. Try it: attach a flag or arm to make it wave, or use it to steer and point a moving model.

The littleBits RGB LED is an adjustable colour light — turn its red, green and blue channels with the included screwdriver to mix almost any colour you like. It's a favourite for adding a personal touch to a build, alongside our other output Bits. Try it: match the light to the colour of your creation, or fade between colours as part of a display.

The littleBits number Bit displays information about the signal it receives on a two-digit, seven-segment screen. In read mode it shows a value from 00–99 or a voltage from 0.0–5.0; in count mode it counts up or down with each trigger and can be reset — a great bridge into data and maths within a circuit. Pair it with the rest of our littleBits output modules. Try it: use count mode with a button to tally presses, or read mode with a sensor to display a live reading.

The littleBits LED (light-emitting diode) is a small board that shines a clear green light — the go-to Bit whenever you want to light something up, and often the first output students ever use. Explore the rest of our littleBits output modules to add sound and motion too. Try it: connect it straight to a USB power Bit to make the simplest possible littleBits circuit.

The littleBits DC motor spins a small shaft you can attach wheels, arms or card to — the go-to Bit for adding movement to a build. It's tethered, so you can place the motor exactly where it's needed, and it pairs with the rest of our output Bits. Try it: add a wheel to build a moving vehicle, or attach card to make a spinning display.

The littleBits buzzer does exactly what its name suggests — it makes an attention-grabbing sound whenever it receives an ON signal. It's a quick, satisfying output for feedback and alerts, and works with the rest of our output Bits. Try it: build your own doorbell, timer or alarm, or pair it with a button to send signals in Morse code.

The littleBits bargraph shows how much signal a circuit is receiving using five coloured LEDs that light up in sequence — a simple, visual way for students to "see" an otherwise invisible signal. It's one of the most useful littleBits output modules for understanding how inputs work. Try it: pair it with a pressure sensor to build your own strength-o-meter.

The littleBits toggle switch is a simple manual switch: flip it one way to send an ON signal, the other way for OFF. It's the most straightforward way to give students hands-on control of when a circuit runs, and works with the rest of our littleBits input modules. Try it: use it as a simple power switch for a build, so a light, motor or buzzer only runs when you want it to.

The littleBits threshold only lets a signal through once it passes a level you set with the screwdriver — turning a gradually changing input into a clear on/off point. It's a great introduction to decision-making in a circuit, and sits with our other input Bits. Try it: put it after a light sensor so a lamp only switches on once a room gets dark enough, not the moment the light dips.

The littleBits temperature sensor measures how warm or cold it is and sends a signal that changes with the temperature — a simple way to bring real-world data into a circuit. Pair it with the rest of our littleBits input modules to build responsive projects. Try it: connect it to a number Bit to make a digital thermometer, or to a buzzer for a "too hot" alarm.

The littleBits slide dimmer is a slider that sends a smoothly changing (analogue) signal as you move it — perfect for fine control over things like brightness, volume or motor speed. It's one of the most useful littleBits input modules for adding a "dial" to a build. Try it: place it before an LED to fade the light up and down, or before a DC motor to control how fast it spins.

The littleBits remote trigger lets students control a circuit with an ordinary infrared remote — point almost any remote at its sensor and press a button to activate the Bits that follow. It adds a wireless element to builds and works with the rest of our littleBits input modules. Try it: build a remote-controlled light, or a gate that opens at the press of a button.

The littleBits pulse is like an electronic heartbeat: it sends out a steady stream of ON signals, and you can speed them up or slow them down with the included screwdriver. It's a simple way to add timing and rhythm to a circuit alongside our other input Bits. Try it: use it to make an LED blink steadily, or to drive a repeating motion in a build.

The littleBits pressure sensor is touch-activated — give its pad a squeeze and the harder you press, the more signal it sends. It's a hands-on way to introduce variable (analogue) inputs, and works with any of our littleBits input modules. Try it: put it before a vibration or DC motor to control how much something shakes or spins.

The littleBits motion trigger works like the sensor on an automatic door: when something moves nearby, it sends an ON signal to the Bits that follow. It's sensitive enough for quick, reliable detection in classroom builds, and pairs neatly with the rest of our input Bits. Try it: add a few LEDs to build a motion-activated security light, or a buzzer for a simple room alarm.

The littleBits light sensor reacts to how much light is falling on it, with "light" and "dark" modes and a screwdriver-adjustable sensitivity — so the same Bit can trigger a circuit when a room brightens or when it goes dark. It's one of the most useful littleBits sensors for real-world projects. Try it: pair it with an LED to make an automatic night light, or with a bargraph to watch the reading change as you cover the sensor.

The littleBits envelope shapes the loudness of a sound over time, turning a plain tone into something closer to a real instrument. Two dials set the "attack" (how quickly the sound rises) and "decay" (how quickly it fades), and a third connection lets you trigger it from a keyboard or another Bit. It's part of the littleBits synth family within our output Bits. Try it: place it after an oscillator and trigger it from a keyboard to play expressive, piano-like notes.

The littleBits button is a big, springy push-button that turns your circuit on while it's held and off when you let go — one of the simplest ways to give students hands-on control of a build. Combine it with our littleBits input modules to trigger lights, sound and motion. Try it: snap a buzzer after the button to tap out Morse code, or use it to switch an LED or motor on demand.

The littleBits wire Bit lets you physically separate parts of a circuit, so you can position Bits exactly where you want them — like putting a light at the top of a model while the controls sit at the base. It's a building block of neat, flexible layouts, alongside our other wire and logic Bits. Try it: use it to run a signal up, around or across a larger build without everything sitting in one line.

The littleBits split sends a single input to two wired outputs, giving you flexible ways to branch a circuit — for example, using one control to drive two separate parts of a build. It sits with the rest of our littleBits wire and logic modules. Try it: use one keyboard to control two oscillators, or simply treat it as a wire Bit when you only need one output.

The littleBits latch turns a momentary input — like a button or trigger — into an ON/OFF switch. Press once to turn it on, press again to turn it off, so a quick tap can hold a state. It's a useful logic building block within our wire and logic Bits. Try it: put a sound trigger before the latch and a light after it, then turn the light on and off just by snapping your fingers.

The littleBits inverter is a simple logic Bit that flips the signal it receives: an ON becomes an OFF, and an OFF becomes an ON. It's a gentle first taste of the logic behind computing, and pairs with our other wire and logic Bits. Try it: place it between two LEDs after a pulse so they blink back and forth, like the lights on top of a police car.

The littleBits fork splits the output of one Bit to as many as three others at once, so you can trigger several things together — light, sound and motion all firing from a single input. It's one of the handiest wire and logic Bits for building richer circuits. Try it: send one button press to an LED, a buzzer and a motor at the same time.

The littleBits USB power is a small but capable power Bit — connect the included USB cable to a computer or phone charger and it sends power to your whole circuit, with a red LED to show when it's on. You'll get around 500 mA from a computer's USB port, or up to about 1 A from a USB wall adapter. Browse the rest of our littleBits power modules for other options. Try it: connect it to an LED for the simplest possible littleBits circuit. (It supplies power only — there's no data connection.)

littleBits bitShoes are small hook-and-loop mounts that stick to the bottom of your Bits, so you can attach a circuit to fabric, felt, cardboard and other materials — no tape or glue needed. They're a simple way to build Bits into wearables, puppets and craft projects, and are part of our littleBits accessories. Try it: stick Bits onto a felt banner or a cardboard model so a finished invention holds together and can be handled. HOOK & LOOP Shoes come with an adhesive-backed Hook & Loop strip. The strip can be cut to any size you desire and affixed to clothing or fabric to enhance your wearable project. ADHESIVE Shoes can be secured onto any surface -- paper, cardboard, plastic – you name it! [Adhesive backing is one-time use only.] MAGNET shoes allow you to adhere your circuit to any magnetic surface--like your fridge! VARIETY PACK comes with 5 Adhesive, 5 Magnet, and 5 Hook & Loop; everything you need for experimentation and building.

littleBits mounting boards hold a finished circuit together so students can pick it up, turn it over and carry it without it falling apart. Press the feet of your Bits into the holes, and use the corner holes to fix a build permanently to a project. Boards come two to a pack and can be tiled for larger circuits — a staple of our littleBits accessories. Try it: mount a circuit vertically or upside down for a display, or fix one inside a cardboard build.

The littleBits motorMate makes it easy to attach wheels, card, paper and other materials to the DC motor — just slide it onto the shaft. A LEGO® axle also fits the end, so it plays nicely with brick-based builds. It's a small but handy part of our littleBits accessories. Try it: fit it to the DC motor to drive a wheel, a spinner or a paper mechanism.

The littleBits Brick Adapter is the simple bridge between your littleBits circuits and the LEGO® bricks students already build with. Snap the adapters onto bricks and press your Bits into place, and a LEGO® model can suddenly light up, make sound or move — a quick way to turn a static build into a working invention. What's included: 8 brick adapters in each pack — 4 stud adapters and 4 socket adapters Holds up to 24 littleBits modules across a build Studs clip under a brick so Bits mount below; sockets clip on top so Bits sit above What students practise: Combining electronics with familiar construction materials to design and prototype Adding light, sound and motion to a model and testing how it behaves Open-ended engineering — building anything from a LEGO® robot to a motorised vehicle The Brick Adapter is a low-cost, hard-wearing accessory that works right across the littleBits range, so it's an easy add-on for classrooms and makerspaces that already use LEGO®. LEGO® is a trademark of the LEGO Group, which does not sponsor, authorise or endorse this product.

The littleBits battery + cable includes a 9 V alkaline battery and a cable that connects it to the power Bit — snap it in, flip the switch and your creations come to life. It's an easy way to make a build portable, and sits alongside our other power Bits. Try it: use it with the power Bit to run a circuit away from a computer or wall socket. (Designed for the power Bit — it won't work with the USB or coin-battery Bits.)
