The "poor man's" accelerometer! Tilt sensors are switches that can detect basic motion/orientation. The metal tube has a little metal ball that ro...

Plastic wheel with a cutout specially designed to allow attachment to our larger continuous rotation servo . Makes it easy to get your robot rollin...

FSRs are sensors that allow you to detect physical pressure, squeezing and weight. They are simple to use and low cost. This sensor is an Alpha MF0...

This SHARP distance sensor bounces IR off objects to determine how far away they are. It returns an analog voltage that can be used to determine ho...

CdS cells are little light sensors. As the squiggly face is exposed to more light, the resistance goes down. When it's light, the resistance is abo...

Diffused 5mm tri-color LED with separate red, green and blue LED chips inside! Nice indicator, and fun to color-swirl. 60 degree viewing angle. We...

IR sensor tuned to 38KHz, perfect for receiving commands from a TV remote control. Runs at 3V to 5V so it's great for any microcontroller. To use,...

This high-torque standard servo can rotate approximately 180 degrees (90 in each direction). You can use any servo code, hardware, or library to c...

This servo rotates fully forward or backward instead of moving to a position. You can use any servo code, hardware, or library to control these se...

75 flexible stranded core wires with stiff ends molded on in red, orange, yellow, green, blue, brown, black and white. These are a major improveme...

A real stand with sponge and solidly-built sheet metal holder prevents your iron from 'rolling away' or burning a hole in the table. If you're star...

Used along with the solder sucker to clean up soldering messes. Wick really comes in handy when soldering or desoldering surface-mount parts. Even...

We've upgraded our basic 'adjustable' wire strippers to these multi-sized wire strippers. They include: 20-30 AWG strippers, wire cutters, 'plier'...

Simple needlenose pliers for twisting, pulling and pliering your project.

If you want to make a kit you'll need some solder. This 100g (about 1/4 lb) spool is just the right amount, not too much (like 1 lb spools) and no...

A third-party SNES (Super Nintendo/Famicom) controller. Works great with Fuzeboxen as well!

This is a preprogrammed Atmega328P chip, useful if you want to make your own Arduino-compatible or repair a damaged chip on an existing Arduino UN...

Useful for larger electronic projects, including the YBox2 kit

“How could something so simple be so useful?” We heard once that in the 4th millennium BC some guy asked the person who invented the wheel that q...

I found these high-quality battery clips. They're molded plastic so they won't tear like cheap clips, and they cover the battery terminals to prev...

Just about all electronics use TTL serial for debugging, bootloading, programming, serial output, etc. But it's rare for a computer to have a seri...
