Once you have mastered the basic blinking leds, simple sensors and buzzing motors, it’s time to move on to bigger and better projects. That usually involves combining bits and pieces of simpler sketches and trying to make them work together. The first thing you will discover is that some of those sketches that ran perfectly by themselves, just don’t play well with others. There are ways to effectively juggle multiple tasks on an Arduino. This series of guides will show you how.
Traveling or on the road, sometimes finding an open network to get online and finish a job is more important than lunch or a nap. MASLOW (Mini Adafruit System Locates Open Wireless) is a tiny battery-powered WiFi detector with a 3D-printed enclosure…assemble one yourself and clip it to your laptop bag.
If you're like me, you loved the Adafruit Daft Punk helmet that showed up on our blog a few weeks ago... but, as my 3D printer is a little bit smaller than a TAZ, and funds and time are limited, I thought for Halloween I would make my own version, based around a $5 mask from Party City that looks a little bit like Cobra Commander.
Ever wanted to create your own game show environment. Hack a Duo Pop Game infrared (IR) receiver so you can create your own game show system using wireless poppers with a PC or Mac computer. This modification allows the IR receiver to interface with both PC and Mac game show software via the USB. This project leverages lessons learned from previous tutorials at adafruit.com involving 1) IR decoding and 2) the virtual USB library. This is a great weekend project for learning about wireless IR protocols and USB communication using the Pro Trinket.
If you have a Pro Trinket you probably know it's the perfect little size for a portable project. This LiPoly backpack makes it really easy to do! Instead of wiring 2 or 3 boards together to make a charging system, this little PCB sits on top of the Pro Trinket and allows a LiPoly/LiIon battery to plug in. When the Pro Trinket USB port is powered, the battery is recharged automatically. Unplug the USB port and the Pro Trinket will switch over to the rechargeable battery.
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 Close Encounters hat is a nod to the incredible movie -- with lights and sounds that mimic the mother ship, all stowed under the brim. A vibration sensor triggers the action, while the NeoPixels and Piezo buzzer provide the show. Get ready to change up that next kiss or rock a quiet movie theater.
