Build and customize your very own open-source button grid controller. This DIY kit comes with delicious translucent button pads, driver boards, diffused white LEDS and a custom laser cut enclosure. The result is a sturdy and elegant but also super-hackable controller device for music, video…or something else???
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.
These LED panels take care of all the work of making a big matrix display. Each panel has six 8x8 red matrix modules, for a 16x24 matrix. The panel has a HT1632C chip on the back with does all the multiplexing work for you and has a 3-pin SPI-like serial interface to talk to it and set LEDs on or off. There's a few extras as well, such as being able to change the brightness of the entire display, or blink the entire display at 1 Hz.
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.
Incorporating Bluetooth in a project no longer requires the most advanced microcontroller or lots of code…our Bluefruit LE UART Friend and accompanying app for iOS and Android make it easy! Building upon our popular "Kaleidoscope Eyes" NeoPixel goggles project, this guide shows how Bluetooth LE can be used even with the most modest setup.
Instead of having a computer that talks thru the Arduino to a chip for programming, instead the Arduino itself programs the chip. This means you can program chips without having a computer involved. The good news about this technique is that it is incredibly fast, you can program chips 10x faster than with a computer and without having to type anything in.
I2C is incredibly popular because it uses only 2 wires, and like we said, multiple devices can share those wires, making it a great way to connect tons of sensors, drivers, expanders, without using all the microcontroller pins. The only bad news about I2C is that each I2C device must have a unique address - and the addresses only range from 0 to 127 (aka 0 to 0x7F hex). Since we deal with so many I2C devices we thought it would be handy to have a table with all the most common sensors and modules we encounter, and their I2C address!
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.
