Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference, as well as calculations to handle any non-linearities. For a long time we've suggested our MAX31855K breakout, which works great but is only for K-type thermocouples. Now we're happy to offer a great new thermocouple amplifier/converter that can handle just about any type of thermocouple, and even has the ability to give you notification when the temperature goes out of range, or a fault occurs. Very fancy! This converter communicates over 4-wire SPI and can interface with any K, J, N, R, S, T, E, or B type thermocouple
Interpretting datasheets is fraught with peril in the best of circumstances. Even chips from the same vendor can use varying terminology and units, often in an attempt to hide short-comings in individual devices. Trying to compare chips across vendors adds another layer of complication. We'll help you decipher the key terms around gyroscopes in this learning guide.
Spice up your Feather project with a beautiful 2.4" touchscreen display shield with built in microSD card socket. This TFT display is 2.4" diagonal with a bright 4 white-LED backlight. You get 240x320 pixels with individual 16-bit color pixel control. It has way more resolution than a black and white 128x64 display. As a bonus, this display comes with a resistive touchscreen attached to it already, so you can detect finger presses anywhere on
To get precision and accuracy out of your platinum (PT100 or PT1000) RTD you must use an amplifier that is designed to read the low resistance. Better yet, have an amplifier that can automatically adjust and compensate for the resistance of the connecting wires. If you're looking for a great RTD sensor, today is your lucky day because we have a lovely Adafruit RTD Sensor Amplifier with the MAX31865 breakout for use with any 2, 3 or 4 wire PT100 RTD!
The VL53L0X is a Time of Flight distance sensor like no other you've used! The sensor contains a very tiny invisible laser source, and a matching sensor. The VL53L0X can detect the "time of flight", or how long the light has taken to bounce back to the sensor. Since it uses a very narrow light source, it is good for determining distance of only the surface directly in front of it. Unlike sonars that bounce ultrasonic waves, the 'cone' of sensing is very narrow. Unlike IR distance sensors that try to measure the amount of light bounced, the VL53L0x is much more precise and doesn't have linearity problems or 'double imaging' where you can't tell if an object is very far or very close.
If you've already got an Amazon Alexa or Echo dot in your home or office, you can easily add your very own devices. In this quick project we'll show how to use an Adafruit ESP8266 Feather HUZZAH to control NeoPixels or a relay. You can easily adapt the code to add any number of devices to a single Feather for all sorts of interactive home automation projects with ease!

This Bonnet uses I2S a digital sound standard, so you get really crisp audio. The digital data goes right into the amplifier so there's no static like you hear from the headphone jack. And it's super easy to get started. Just plug in any 4 to 8 ohm speakers, up to 3 Watts, run our installer script on any Raspberry Pi, reboot and you're ready to jam!
The Snake Eyes Bonnet is a Raspberry Pi accessory for driving two 128x128 pixel OLED or TFT LCD displays, and also provides four analog inputs for sensors. It's perfect for making cosplay masks, props, spooky sculptures for halloween, animatronics, robots...anything where you want to add a pair of animated eyes!
Add motion, direction and orientation sensing to your Arduino project with this all-in-one 9-DOF sensor. Inside the chip are three sensors, one is a classic 3-axis accelerometer, which can tell you which direction is down towards the Earth (by measuring gravity) or how fast the board is accelerating in 3D space. The other is a 3-axis magnetometer that can sense where the strongest magnetic force is coming from, generally used to detect magnetic north. The third is a 3-axis gyroscope that can measure spin and twist. By combining this data you can REALLY orient yourself.
For many microcontrollers, adding audio input is easy with one of our analog microphone breakouts. But as you get to bigger and better microcontrollers and microcomputers, you'll find that you don't always have an analog input, or maybe you want to avoid the noise that can seep in with an analog mic system. Once you get past 8-bit micros, you will often find an I2S peripheral, that can take digital audio data in! That's where this I2S Microphone Breakout comes in.
Pocket-sized fun is the name of this game, with the Joy Bonnet - our most fun Bonnet ever (no we didn't even think that was possible, either!) This Bonnet fits perfectly on top of your Raspberry Pi Zero (any kind) and gives you adorable hand-held arcade controls. Once you install our script onto your Pi, the controls will act like a keyboard, for easy use with any emulator or media player.
Using 900Mhz (or 425Mhz) RF for long-range communications between the transmitter and the receivers, this general purpose controller will make your wireless triggering wishes come true! Plus, you get to use a rotary encoder knob to scroll menu sets, and punch in your commands on the lighted 4x4 Trellis keypad.
