Ada Twist, Scientist is a picture book by Andrea Beaty and illustrated by David Roberts. Ada has always been insatiably curious — why are there pointy things on a rose? Why are there hairs growing ...

The Feather 32u4 Bluefruit LE with Stacking Headers combines an ATmega32u4 microcontroller with a Bluetooth Low Energy module, USB connectivity, and LiPo battery charging — with stacking headers pr...

The SparkFun Inventor’s Kit (SIK) is a great way to get started with programming and hardware interaction with the Arduino programming language. The SIK includes everything you need to complete ...

The Speaker Cubelet contains a small speaker and an amplifier that will chirp according to the block’s data value. Cubelets are magnetic blocks that can be snapped together to make an endless va...

The Blocker Cubelet is a basic building block that “blocks” data from its neighbors. It still passes power, but effectively stops communication and can insulate one side of a robot from another.Cub...

If you use the SparkFun Inventor’s Kit in a classroom or workshop setting, you know that when a bunch of people get their hands on the same kit, things get lost/broken. That’s why we offer the Spar...

The Rotate Cubelet is an action block in the Cubelets modular robotics system. One face spins at a rate determined by the block's input values, allowing it to act as a motor output in snap-together...

The Flashlight Cubelet is an action block for the Cubelets modular robotics system. It emits a focused beam of white light from a powerful LED, with brightness proportional to its input value — hig...

The Inverse Cubelet is a "think" block in the Cubelets modular robotics system. It calculates the opposite of the values it receives — averaging its inputs and outputting one minus that average. Us...

The Maximum Cubelet is a "Think" block in the Cubelets robot construction system. It accepts multiple input values and passes along only the greatest one, acting as a filter for sensor data. Use it...

The Brightness Cubelet has an analog photocell that responds to varying light conditions and detects the amount of light hitting it’s sensor. Expect values near zero in a dark room, and value...

The Temperature Cubelet contains a tiny thermometer (actually, a thermistor) that detects temperature. It’s calibrated to output a 0 in freezing conditions and 255 in hot, sunny conditions of about...

The Distance Cubelet detects how far it is from an object. It uses infrared light and is accurate between 10 and 80 cm. The sensor is directional, so outputs the distance to the object in fro...

A 10-pack of cables with an alligator clip on one end and a bare hookup pigtail (male pin) on the other. These cables make it easy to connect alligator clips directly into breadboards, development ...

The Quick 957D is a hot air soldering rework station with an internal pump and heater that delivers a steady stream of temperature-controlled hot air. It is designed for removing and replacing surf...

The Arduino Mega 2560 Rev3 is a microcontroller board based on the ATmega2560, offering significantly more I/O than standard Arduino boards. With 54 digital I/O pins, 16 analog inputs, and 4 hardwa...

This Digital LED Voltmeter measures the voltage at a particular point of the system it has been hooked up to and then provides a readout on its three 7-segment LEDs. This voltmeter is able to provi...

How can your robot rule the world with an iron fist if it doesn't have a hand? This LG-NS robot gripper makes a great addition to a small arm or mobile base. The gripper features injection mo...

This is a high quality plastic servo horn. It fits DF series servos. Made specifically for DF series servos. SPECIFICATIONS Outside diameter: 20mm(0.79") Center hole diameter:...

The Xcelite 8-in-1 Screwdriver Set provides eight high-quality bits in a single ergonomic tool. Each bit is easily accessible with a spring-loaded magnetic housing that holds the seven included bit...
