Resistors are a good thing, in fact, they\'re actually crucial in a lot of circuit designs. The only problem seems to be that resistors disappear i...

This 200 pulse per rotation rotary encoder outputs [gray code](http://en.wikipedia.org/wiki/Gray_code) which you can interpret using a microcontrol...

This is a basic, 4-digit 7-segment display - white in color. It has a common anode. The display features one decimal point per digit, and individu...

Schottky diodes are known for their low forward voltage drop and a very fast switching action. This 1A 40V Schottky diode is ideal for use with mo...

These are massive single pole - double throw (SPDT) sealed relays. This means that when current is applied to the coil it throws a simple changeove...

These are the same RGB LEDs that were used for the old WS2801 breakout board. They\'re great when you need a lot of color from not a lot of board ...

A simple SMD slide switch. Perfect for when you need access to a setting or a power switch from the edge of a PCB buried deep within a project. ...

If you ever find yourself connecting handfuls of resistors to the ground bus of your breadboard, you may consider these SIL-packaged resistors as a...

Ever hear of a thing called RGB? Red, Green, Blue? How about an RGB LED? These 5mm units have four pins: one for each color and a common anode. Use...

This right-angle tactile switch has a great \'click\' to it. Also, because it\'sa through-hole design it\'s very sturdy. Mount it on the edge of y...

Check out these big 10mm through-hole LEDs! The opaque epoxy package causes these LEDs to have a soft, diffuse glow. **Features:** * 465-470...

Potentiometers are incredibly useful, whether you\'re controlling the volume on your stereo or the \'mood lighting\' in your room. The problem wit...

This is a small device called a [reed switch](http://en.wikipedia.org/wiki/Reed_switch). When the device is exposed to a magnetic field, the two fe...

Rubber feet raise your PCB or project up off your desk. This helps prevent short circuiting from bits of scrap wire floating about or setting a pro...

This is a 34\' roll of thermal printing paper for use with our thermal printer. This roll is smaller than you find at most office supply stores so...

The seven band graphic equalizer IC is a CMOS chip that divides the audio spectrum into seven bands. 63Hz, 160Hz, 400Hz, 1kHz, 2.5kHz, 6.25kHz and ...

This is a simple LED-illuminated tactile button with a clear cap. It\'s just like a basic tactile button, but it lights up blue! So now you can get...

This is a simple LED-illuminated tactile button with a red cap. It\'s just like a basic tactile button, but it lights up red! So now you can get v...

This is a simple LED-illuminated tactile button with a green cap. It\'s just like a basic tactile button, but it lights up green! So now you can g...

This is a simple LED-illuminated tactile button with a clear cap. It\'s just like a basic tactile button, but it lights up white! So now you can ge...

If you\'ve ever wondered how to control the headlight of a car from a microcontroller, a MOSFET is what you need. The IRF5305 is a very common MOS...
