9V + cable kit
- This package contains a 9v alkaline battery and a cable to connect it to the power Bit. Connect it up and then flip the switch to power all of your creations!..
- You can now easily incorporate programming into your littleBits circuits! It’s everything you know and love about Arduino without the breadboarding, soldering or wiring. Simply plug into your computer, snap together needed modules, and program away! You focus on the code, we'll cover the electronics..
- The bargraph is one of our favorite Bits: it has five LEDs in different colors that light up to show you how much signal the module is receiving. Try it with a pressure sensor to make your own strength-o-meter...
bend sensor kit
- The bend sensor turns on as you flex the long strip. To send signal to your output Bits, bend the strip down, towards the Bit's feet. But make sure not to crease it: that could damage your Bit! Try it with a bargraph to test its sensitivity...
- bitSnaps are the color-coded, magnetic connectors found on either end of all littleBits modules. Use these to make your own modules by attaching bitSnaps to either end of your printed circuit board. They allow you to snap modules together with ease and prevent you from connecting modules the wrong w..
- 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 three others, oriented in different directions. Use it when you want to trigger light, sound and motion at the same time...
brick adapter kit
- The Brick Adapter enables you to easily snap littleBits modules to LEGO® bricks. Each pack comes with brick adapter studs and sockets...
bright LED kit
- The bright LED (or "Light-Emitting Diode") is a small module that puts out a big light. Just like our other LED modules, it's a great way to shed some light on your creations. Choose the bright LED when you want a LOT of bright white light...
- A powerful brushless motor specially designed for the AR.Drone, is supplied with its own electronic speed controller, to guarantee high performance and a long life. The motor has a power rating of 15 Watts and rotates at 28,000 revolutions per minute when hovering. It represents 3,300 RPM at the pro..
- The button Bit is a classic: big, round and springy for comfortable pressing! Push to turn your creation on, and release to turn it off. Snap a buzzer in place after your button to sound out signals in morse code!..
- 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!..
Coin Battery kit
- The coin battery is a small rechargeable power source. It can power most littleBits, but the mechanical Bits will deplete it quickly. Just flip the switch to turn it on and let power flow; when it's out of juice, plug it in with the included micro USB cable until the light goes from yellow to green...
DC motor kit
- The DC (or "Direct Current") motor rotates a shaft when you send it an ON signal. It even has a switch to set the direction of rotation! It also includes the motorMate-- an accessory that makes it easy to attach wheels, paper, cardboard, and lots of other materials to the motor. Simply slide it on t..
- The littleBits delay module takes incoming audio and repeats it, like an echo. It has two knobs: "time", which sets the delay length between a sound and its repetition, and "feedback", which controls how many times the sound repeats. Delays can be long and spacey, like shouting into the Grand Canyon..
- Our dimmer Bit lets you control your creations with a simple knob. Turn it clockwise to send more signal to the following Bits. Try using it to control how much your vibration motor is buzzing and bouncing around...
double AND kit
- The AND Bit is a logic gate with two inputs. Just like its name implies, it sends an ON signal from its output only when input one AND input two are both receiving an ON signal...
double OR kit
- The OR Bit is a logic gate with two inputs. Just like its name, if input one OR input two is receiving an ON signal, then it sends an ON signal from its output...
- The envelope modifies the loudness contour of a sound. It takes a sound input and shapes it into something you'd hear from an acoustic musical instrument, like a piano or saxophone. This envelope has two controls: "attack", which is how long it takes to ramp up to maximum volume, and "decay", which ..
- The fan Bit is just what you'd think: a small electric fan tethered to a littleBits module. It's great for those hot summer nights. Use our little fan to create fluttering movement in your creations or just to keep yourself cool...
- 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 to give the impression that a sound is “brighter" (more high frequencies) or “darker” (more low frequencies.) The "cutoff" knob sets ..
- 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 Hardware Development Kit (HDK) is the quickest way to get started developing your own module for the bitLab. The two proto modules allow you to connect to PCBs and breadboards, while the perf module allows you to build a small circuit right on the module. When you're ready to design your own PCB..
- The inverter is a very contrary logic Bit. It sends out the opposite of whatever it receives: send it an ON signal, and the inverter changes it to an OFF signal, or vice versa. Try putting it between two lights after a button: clicking will make the LEDs blink back and forth, like the lights on top ..
IR LED kit
- The IR LED (or infrared light-emitting diode) module sends out light with longer wavelengths than visible light, similar to the light in your remote control. It’s invisible to the eye, but many digital cameras can see it! Try using it to activate the light sensor or remote trigger...
- The keyboard lets you play melodies- it features 13 switches that make up an entire octave of notes. It has two 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 ran..
- Use the latch to turn any momentary input, like a button or a trigger module, into an ON/OFF switch, like a toggle! If you place a button in front of the latch, pressing the button once will turn it ON, and pressing it again will turn it OFF again. Or for even more fun, place a sound trigger in fron..
- The LED (or "Light-Emitting Diode") Bit is a very small board that shines a nice green light. It's our go-to when you want to light something up...
light sensor kit
- The 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 ad..
light wire kit
- The light wire Bit is almost four feet long and its entire length glows a soft blue. It's made of special stuff called "electroluminescent wire," which is great to form into glowing shapes. It's best to use in the dark. We like to use it for wearable accessories when we go to parties!..
LittleBits Arduino Coding Kit
- This littleBits kit contains 8 of our favorite prototyping modules. It’s everything you need to get started with electronics and programming. Make your own Etch-a-Sketch™! Program a visual display! We’ll walk you through the basics using the Arduino programming environment, without the breadboarding..
