How It Works This envelope has 2 controls: "attack," which is how long it takes to ramp up to maximum volume, and "decay," which is how long it takes to go down to silence again. You can use its third bitSnap to...

The filter has the most effect on the sound’s character or "timbre." It affects the timbre by changing the relative volume of certain frequencies in the sound. Use it with other synth Bits to give the impression that a sound is...

How It Works. The keyboard has 2 modes: "press" (which only produces output when you press a switch) and "hold" (which will hold the last note you played). It also features an octave control which changes the playable...

The micro sequencer sends out voltages based on the position of each of the 4 "step" knobs. Connect it to an oscillator and it will step through the "sequence" consecutively to make a melody (the LEDs tell you which...

You can use the microphone Bit like a small megaphone, or even to turn sounds into light or motion! This Bit translates sounds into a language that littleBits circuits can understand. How It Works The microphone Bit takes sound from its...

The littleBits mix Bit allows you to combine 2 inputs and send them to a single output. It also has a volume control for each of its inputs -- that's where the 'mixing' comes in. Use it to play 2 oscillators on a single...

With this Bit, you can control your circuits with motion. The motion trigger is similar to the sensor on an automatic door: when someone is moving nearby, it sends an ON signal to the following Bits. It's very sensitive, so don't...

The MP3 player Bit allows you to play your very own MP3 files using littleBits. Sending a signal to the MP3 player can make it work as a media player, sampler, or looper. Just load the MP3 files you want onto the provided SD card and...

How It Works. The oscillator Bit features a "pitch" knob to adjust its output tone and a "tune" dial for adjusting the tuning when using with the keyboard. It also features a mode switch that selects between...

The pressure sensor is a touch-activated Bit - give its pad a little squeeze to activate it. The more pressure you apply, the more signal it sends out. Put it in front of a vibration motor to control how much it shakes! Inventions With...

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,...
