What's better than a single LED? Lots of LEDs! A fun way to make a small display is to use an 8x8 matrix or a 4-digit 7-segment display. Matrices like these are 'multiplexed' - so to control all the seven-segment LEDs you need 14 pins...

This cable will let you swap out the stock 150mm long flex cable from a Raspberry Pi Camera (either 'classic' or 'NoIR' type) for a different size. Works great, just carefully open the connector on the Pi and slip this one in.

An anemometer is a device used for measuring wind speed, and is a common weather station instrument. This well made anemometer is designed to sit outside and measure wind speed with ease. To use, connect the black wire to power and signal ground, the...

You just found the perfect I2C sensor, and you want to wire up two or three or more of them to your Arduino when you realize "Uh oh, this chip has a fixed I2C address, and from what I know about I2C, you cannot have two devices with the same address on...

The long awaited BME680 from Bosch gives you all the environmental sensing you want in one small package. This little sensor contains temperature, humidity, barometric pressure, and VOC gas sensing capabilities...

This sensor can detect flexing or bending in one direction. They were popularized by being used in the Nintendo PowerGlove as a gaming interface. These sensors are easy to use, they are basically resistors that change value based on how much their...

The latest Raspberry Pi computers come with WiFi and Bluetooth, and now you can add even more radio options with the Adafruit Radio Bonnets! Upgrade your Raspberry Pi with a LoRa / LoRaWAN radio, so it can communicate over very long distances...

This super small mono amplifier is surprisingly powerful - able to deliver up to 2.5 Watts into 4-8 ohm impedance speakers. Inside the miniature chip is a class D controller, able to run from 2.0V-5.5VDC. Since the amp is a class D, its very efficient...

Make a small linear display with a glowing yellow-green color using this elegant LED bargraph. Only 1" long, it is quite visible but not so large it wont plug into a breadboard! 10 LEDs are contained in the plastic body. This display is bright, beautiful...

Make a small linear display with a glowing bright yellow color using this elegant LED bargraph. The color on this bargraph is similar to our amber display but just a bit brighter and with a bit more yellow mixed in. Only 1" long, it is quite visible but...

Make a small linear display with a glowing red color using this elegant LED bargraph. Only 1" long, it is quite visible but not so large it wont plug into a breadboard! 10 LEDs are contained in the plastic body. This display is bright, beautiful and...

Make a small linear display with a glowing white color using this elegant LED bargraph. Only 1" long, it is quite visible but not so large it wont plug into a breadboard! 10 LEDs are contained in the plastic body. This display is bright, beautiful and...

Make a small linear display with a glowing blue color using this elegant LED bargraph. Only 1" long, it is quite visible but not so large it wont plug into a breadboard! 10 LEDs are contained in the plastic body. This display is bright, beautiful and...

Make a small linear display with a glowing pure-green color using this elegant LED bargraph. This pure-green color is much more vivid and closer to blue than 'yellow green' LEDs. Only 1" long, it is quite visible but not so large it wont plug into a...

Make a small linear display with a glowing amber color using this elegant LED bargraph. The color on this bargraph is similar to our yellow display but just a bit darker and with a bit more orange mixed in. Only 1" long, it is quite visible but not so...

Make a scrolling sign, or a small video display with this 8x8 square gridded pure green LED matrix. Only 1.2" on a side, it is quite visible but not so large it won't plug into a breadboard! There are 16 pins on the side, 8 on each, with 0.1"...

Make a scrolling sign, or a small video display with this 8x8 gridded pixel white LED matrix. Only 1.2" on a side, it is quite visible but not so large it won't plug into a breadboard! There are 16 pins on the side, 8 on each, with 0.1" spacing so...
