Once it's up again, you'll have some new example sketches. If you don't have one yet, go ahead and create it.) Also, restart the Arduino IDE if you already had it open. (The "libraries" folder is usually created in the same "Arduino" folder where you save your sketches.
You can just download the.zip file with the library, unzip it on your computer, and drag the contents into your Arduino libraries folder. Go download Adafruit's NeoPixel library to get started. Pay attention to the labels, as well as the schematic :) Note: Depending on where you buy your "NeoPixels", you may end up with something that has the pins in a different arrangement. (It helps to chant this in your head, if you're doing lots of them.) The arrows should point away from your headers. Solder some male-male headers to the end, with the little arrows on the LED strip pointing away. That leaves you with solderable pads on each end, which will allow you to chain them together after the fact. You can cut the strips to any length you like to do so, make sure you cut across the center of the oblong copper pads. Works with 99% of existing Arduino sketches (anything that doesn't use more than 28K, and doesn't require pins #2 and #7) Dimensions: - Size: 38mm x 18mm x 2mm - Height with MicroUSB: 4mm / 0.16" - Weight: 2.For this tutorial, we'll assume that you're working with LED strips – the simplest way to light up your bike, bar, CPU tower, and so forth. Power with either USB or external output (such as a battery) - it'll automatically switch over On-board green power LED and red pin #13 LED Reset button for entering the bootloader or restarting the program. Up to 16V input, reverse-polarity protection, thermal and current-limit protection. On-board 3.3V power regulator with 150mA output capability and ultra-low dropout. Also has headers for an FTDI port for reprogramming Micro-USB jack for power and/or USB uploading, you can put it in a box or tape it up and use any USB cable for when you want to reprogram. Here's some handy specifications: ATmega328P onboad chip in QFN package running at 3.3V logic 12MHz clock rate, 28K FLASH available USB bootloader with a nice LED indicator looks just like a USBtinyISP so you can program it with AVRdude and/or the Arduino IDE (with a few simple config modifications). The bootloader does not affect RAM usage.
The bootloader on the Pro Trinket use 4KB of FLASH so the maximum sketch size is 28,672 bytes.
The USB connection is for uploading new code only.
This is to keep the Pro Trinket small and inexpensive, you can use any FTDI cable to connect to the FTDI port for a Serial connection. The onboard power supply is a 3.3V regulator and it can provide 150mA output You cannot plug shields directly into the Pro Trinket There is no Serial-to-USB chip onboard. Only the most timing-specific libraries may be affected, check the documentation! The NeoPixel Library works fine at 12MHz. Pro Trinket is programmable using the Arduino IDE as you already set up, and 95% of Arduino projects will work out of the box! Here's some things you may have to consider when adapting Arduino sketches: Pins #2 and #7 are not available (they are exclusively for USB) The Pro Trinket 3V runs at 12MHz, this doesn't affect most projects. However, it uses 3V logic and 12MHz clock which means it's good when you want a lower-power and lower-voltage setup. The Pro Trinket 3V uses the Atmega328P chip, which is the same core chip in the Arduino UNO/Duemilanove/Mini/etc. So it's great once you've finished up a prototype on an official Arduino UNO and want to make the project smaller. The Pro Trinket PCB measures only 1.5" x 0.7" x 0.2" (without headers) but packs the same capability as an Arduino UNO. We also added Optiboot support, so you can either program your Pro Trinket over USB or with a FTDI cable just like the Pro Mini and friends. Like the Trinket, it has onboard USB bootloading support - we opted for a MicroUSB jack this time. That's why we designed Pro Trinket, with 18 GPIO, 2 extra analog inputs, 28K of flash, and 2K of RAM. Trinket's a year old now, and while its been great to see tons of tiny projects, sometimes you just need more pins, more FLASH, and more RAM.
It's like an Arduino Pro Mini with more pins and USB tossed in. Adafruit Pro Trinket - 3V 12MHz Trinket's got a big sister in town - the Pro Trinket 3V! Pro Trinket combines everything you love about Trinket with the familiarity of the core Arduino chip, the ATmega328.
