Description
The sound trigger listens to the noise level in your room, and sends an ON signal when it gets over a certain level. You can make that threshold louder or softer using the included screwdriver. We like to use it with an LED to light up your room when you snap your fingers.
The sound trigger features an electret microphone that triggers a 5V output when the set threshold is reached. The output of the module will remain high for 3 seconds. If the input signal is high, the module functionality is enabled. If the input signal is low, the module function is disabled.

littleBits Button
$17.23 ex GST
($18.95 inc GST)
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 button module will make or break the signal path between two modules. When the button is pressed, the output of the module is directly connected to the signal line input. When not pressed the output of the module is weakly pulled low through a 1meg resistor.
littleBits Envelope
$36.32 ex GST
($39.95 inc GST)
The littleBits 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 is how long it takes to go down to silence again. You can use its third bitSnap[TM] to trigger the envelope from different sources, like the keyboard. [Try it putting the envelope after an oscillator being controlled by a micro sequencer.]
littleBits Light Sensor
$25.41 ex GST
($27.95 inc GST)
The littleBits 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 adjust the sensitivity. Use a bargraph to see how it's working!
littleBits Motion Trigger
$54.50 ex GST
($59.95 inc GST)
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 breathe unless you want to be detected! Try it with some LEDs to create a security light!
littleBits Pressure Sensor
$36.32 ex GST
($39.95 inc GST)
The pressure sensor is a touch-activated module; 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!
littleBits Proximity Sensor
$20.86 ex GST
($22.95 inc GST)
The proximity sensor Bit senses objects in front of it. It can sense if an object is far or near. Try using it to create your own self-navigating car, or a hands-free instrument!
littleBits Pulse
$22.68 ex GST
($24.95 inc GST)
The pulse Bit is like an electronic heartbeat. It sends out a stream of short ON signals, and you can make the speed of the pulses faster or slower using the included screwdriver. It's great for making LEDs blink!
littleBits Remote Trigger
$22.68 ex GST
($24.95 inc GST)
The remote trigger lets you use a common remote control with your modules. Make your littleBits circuit and point your remote control at the remote trigger’s sensor. Then, press any button on your remote control to activate the module. The remote trigger will work with almost any button on a remote that uses infrared light to send signals.
littleBits Bargraph
$23.59 ex GST
($25.95 inc GST)
The bargraph is one of littleBits favourite Bits: The bargraph shows you how much signal the Bit is receiving with a display of 5 light-emitting diodes (LEDs) in different colours. Try it with a pressure sensor to make your own strength-o-meter.
littleBits Buzzer
$24.50 ex GST
($26.95 inc GST)
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!
littleBits DC Motor Tethered
$45.41 ex GST
($49.95 inc GST)
The DC (or "direct current") motor rotates a small shaft you can attach anything to. Try attaching a wheel! Use it to spin, turn, twist, and roll.
littleBits LED
$18.14 ex GST
($19.95 inc GST)
The littleBits 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.
littleBits Number Plus
$49.95 ex GST
($54.95 inc GST)
The number module displays information about the signal it’s receiving from your other modules. It features a two-digit, seven-segment LED display. In the “read” mode, the module displays information about the signal it’s receiving. In the “count” mode, the module counts up or down with each trigger. The counter can be reset by receiving a trigger at the reset bitSnap.
Geek Speak
This updated number module has 2 main modes and 2 settings under each mode. Use the 4-position switch to choose between the modes.
READ MODE: Read mode has two settings: values and volts. The number module reads the voltage on the input bitsnap, then calculates and displays either a value between 00-99 or a voltage between 0.0 - 5.0. The voltage on the output bitsnap is a filtered PWM value that equals the voltage on the input bitsnap.
COUNT MODE: Count mode has two settings: up (from 00-99) and down (from 99-00). A step to the next number happens on input low-to-high transitions. The voltage on the output bitsnap is a filtered PWM value that is proportional to the number on display. For example, if the displayed number is 50 then the output voltage is 50% of 5V, or 2.5V. The RESET bitsnap can be used in this mode to reset the number on display. In the "up" setting, the display resets to "00". In the "down" setting, the display resets to "99". The RESET bitsnap resets the number on low-to-high transitions.
Under the Hood
An Atmega168 is used to constantly read the signal from the switch and determine which mode the module is in. It also reads the buffered signal from the input bitsnap, and sends a PWM signal through a Sallen key filter to the output bitsnap. In "read" mode, the signal from the input bitsnap is passed from the ADC pin to the PWM output. In "count" mode, a step to a new number is triggered on a low-to-high pin-change interrupt on the ADC pin. A PWM lookup table is used to output the corresponding PWM value. The reset is also triggered on a low-to-high transition. The Atmega168 also controls the seven-segment LED display to display the correct value.
littleBits RGB LED
$20.86 ex GST
($22.95 inc GST)
The RGB LED (or "Red-Green-Blue Light-Emitting Diode") Bit is a special light whose colour you can adjust. Use the included screwdriver to adjust each of the colour channels to get almost any colour. Use the RGB LED when you want to match the light to the colour of your creation!
littleBits Servo
$49.95 ex GST
($54.95 inc GST)
The servo is a controllable motor that can swing back and forth, or be turned to a specific position. Try attaching a flag to the servo to make it wave back and forth!
Cross Axle: This servo has a cross axle shaft that works with any littleBits accessory with a cross axle opening.
Hub Mount: Note that this bit is NOT compatible with the following kits. - Space Rover Inventor Kit - Cross axle mechanical arm (not available separately) - Cross axle motorMate (not available separately)
littleBits Battery + Cable
$11.77 ex GST
($12.95 inc GST)
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!
Note: This product is designed for use with the power Bit, and won't work with the USB or coin battery Bits!
littleBits P3 USB Power
$22.68 ex GST
($24.95 inc GST)
The USB power may be the smallest in the series, but it's big enough to send juice to all your creations. Connect a USB cable (included) to your computer or phone charger to start the power flowing. Try it with an LED to make the simplest littleBits circuit. If you're looking for a permanent installation, the USB power adapter enables you to plug your USB power directly into the wall. Using a USB connection to a computer, you have access to 500mA of power for your circuit. When using the USB Wall Adapter, you should have up to 1A of power available. The red LED shows you when the module is powered.
Note: The USB power Bit does not provide a data connection.
littleBits powerSnaps
$11.77 ex GST
($12.95 inc GST)
The powerSnap supplies power to an open input without extra forks, splits, or power supplies. Includes 3 powerSnaps.
Sphero & littleBits USB Cable
$11.77 ex GST
($12.95 inc GST)
A micro USB cable for Sphero & littleBits products. Can be used for plugging into inductive chargers for Sphero SPRK+ and Sphero BOLT and is compatible with Sphero Mini.
Use with littleBits by connecting a PC to your codeBit or USB power bit or for recharging your Lipo battery. The cable is approximately 0.3 meters long and comes in littleBits white.
NOTE: Does not work with the Sphero RVR Battery.
littleBits Fork
$22.68 ex GST
($24.95 inc GST)
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.
littleBits Inverter
$17.23 ex GST
($18.95 inc GST)
The littleBits 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 of a police car!
The lights on top of a police car flash back and forth. A pulse sends a signal to both of the lights, but they flash opposite one another due to the inverter.
littleBits Latch
$18.14 ex GST
($19.95 inc GST)
Use the littleBits 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 front of the latch, and a light after it...then, just snap your fingers!
littleBits micro:bit Adapter
$40.86 ex GST
($44.95 inc GST)
