We are excited to add another product to our growing Adafruit Bluefruit line, this time its the Bluefruit EZ-Link: the best Bluetooth Serial Link device ever made. Like you, we have purchased all sorts of Bluetooth serial link modules, with high expectations - we just wanted something that worked! But nothing ever did exactly what we wanted: there was always some configuration modes to wade through, and using one of those other modules to reprogram an Arduino is impossible. So we did what we always do, we went in and engineered something better. Something that works!
Wear some space on your face and be a constellation for Halloween! This galaxy makeup is inspired by the Cassiopeia constellation and uses five FLORA NeoPixels to light up the night sky across your forehead, affixed with liquid latex. GEMMA and a coincell battery back reside on a hair clip and run the pixels in any color you choose.
Create your own wireless Bluetooth keyboard controller in an hour with the Bluefruit EZ-Key: it's the fastest, easiest and bestest Bluetooth controller. We spent years learning how to develop our own custom Bluetooth firmware, and coupled with our own BT module hardware, we've created the most Maker-friendly wireless you can get!
For low-power microcontroller WiFi, check out the Adafruit CC3000 breakouts and shields. The CC3000 hits that sweet spot of usability, price and capability. It uses SPI for communication (not UART!) so you can push data as fast as you want or as slow as you want. It has a proper interrupt system with IRQ pin so you can have asynchronous connections. It supports 802.11b/g, open/WEP/WPA/WPA2 security, TKIP & AES. A built in TCP/IP stack with a "BSD socket" interface. TCP and UDP in both client and server mode, up to 4 concurrent sockets.
Gemma may be small, but do not be fooled by its size! It's a tiny sewable microcontroller board, built around the Atmel ATtiny85, a little chip with a lot of power. We wanted to design a little sister to the Flora, something that was small enough to fit into any project, and low cost enough to use without hesitation. Perfect for when you don't want to give up your Flora for a small project
The very word "servo" implies feedback-based control. But for most RC servos, that feedback signal is not available outside the servo case. So when controlling them from a microcontroller, you never really know if the servo is doing what you tell it to do. These feedback servos have an extra wire for the feedback signal. This lets you monitor the servo motion to verify that it is working as expected. It also lets you use the servo as an input device.
Introducing the MENTA, a portable minty Arduino-compatible project that fits into a common mint tin. We took our super popular Boarduino series, and wrapped it with a prototyping area into a rounded PCB that slots directly into an Altoids-sized metal tin. We included everything you expect to jump-start your project: a DC power adapter with polarity protection, beefy 1 Amp 5V regulator and 250mA 3.3V regulator for 3.3V devices, green power LED, red blinky LED, ISP-6 standard reprogramming header, FTDI interface plug to connect an FTDI Friend or cable and female header so you can plug standard Arduino-compatible shields in. There's four mounting holes if you want to attach it permanently to a box or plate, and a massive prototyping area so you can have the finished project all fit together in a protective box.
The proto-screwshield is the ultimate breakout board for an Arduino. It combines a prototyping shield with a full set of 3.5mm screw terminal blocks. The protoshield part lets you build custom circuitry and then you can easily & securely connect wires and sensors to the terminal blocks. Great for panel mounts, buttons, sensors, enclosures etc.
If you have a project with any audio, video, graphics, data logging, etc in it, you'll find that having a removable storage option is essential. Most microcontrollers have extremely limited built-in storage. For example, even the Arduino Mega chip (the Atmega2560) has a mere 4Kbytes of EEPROM storage. There's more flash (256K) but you cant write to it as easily and you have to be careful if you want to store information in flash that you don't overwrite the program itself!
This breakout board is the ultimate companion for the VLSI VS1053B DSP codec chip. The VS1053 can decode a wide variety of audio formats such as MP3, AAC, Ogg Vorbis, WMA, MIDI, FLAC, WAV (PCM and ADPCM). It can also be used to record audio in both PCM (WAV) and compressed Ogg Vorbis. You can do all sorts of stuff with the audio as well such as adjusting bass, treble, and volume digitally. There are also 8 GPIO pins that can be used for lighting up small LEDs or reading buttons.
This project is the third revision of the MiniPOV. This version is nearly identical to the last version, MiniPOV2 but uses the serial port (possibly with a USB/Serial converter) instead of a parallel port, for programming. Because the programmer is built into the kit, one does not need a special "microcontroller programmer". This version can be used with PCs (Linux/Unix or Windows) and Macs (running MacOS X and with a USB/serial converter).
If you've ever struggled to use a solderless breadboard with an Arduino, you understand how frustrating it can be! This Arduino clone was designed to solve this problem in an inexpensive DIY fashion. The Boarduino is an Arduino clone: when programmed with the Arduino bootloader, it can talk to the Arduino software and run sketches just like the original.
