littleBits Wire & Logic Modules

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 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 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 micro:bit Adapter connects a BBC micro:bit to your littleBits, so students can add coding to their circuits using free platforms like Microsoft MakeCode or the Python editor. It links the signals from littleBits input and output bitSnaps to the micro:bit's pins — no special libraries needed. Find it among our range of littleBits accessories. Try it: program a micro:bit countdown clock, a light-seeking sunflower, or an obstacle-avoiding robot. (micro:bit required and sold separately.)

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 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.
