Adafruit's Bluefruit HID controller is the easiest way to instantly add an HID keyboard or mouse interface to your project, even without a microcontroller. Did you know that you can also use it to convert a normal wired keyboard to supporting Bluetooth? In this project you'll learn exactly how to do it.. and in the process you'll bring an iconic piece of computing hardware into the modern age. Time to start digging around in your closet for that old IBM PC you haven't seen for a few years, because with Bluefruit and the Model M, "it just clicks".
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!
Pro Trinket combines everything you love about Trinket with the familiarity of the common core Arduino chip, the ATmega328. It's like an Arduino Pro Mini with more pins and USB tossed in, so delicious. Sometimes you just need more pins, more FLASH, and more RAM. That's why we designed Pro Trinket, with 18 GPIO, 2 extra analog inputs, 28K of flash, and 2K of RAM.
The VL6180X 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 VL6180X 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 VL6180X 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.
Add Internet to your next project with an adorable, bite-sized WiFi microcontroller, at a price you like! The ESP8266 processor from Espressif is an 80 MHz microcontroller with a full WiFi front-end (both as client and access point) and TCP/IP stack with DNS support as well. While this chip has been very popular, its also been very difficult to use. Most of the low cost modules are not breadboard friendly, don't have an onboard 250mA 3.3V regulator or level shifting, and aren't CE or FCC emitter certified....UNTIL NOW!
