Our 0.96" color OLED displays are perfect when you need an ultra-small display with vivid, high-contrast 16-bit color. The visible portion of the OLED measures 0.96" diagonal and contains 96x64 RGB pixels, each one made of red, green and blue OLEDs. Each pixel can be set with 16-bits of resolution for a large range of colors. Because the display uses OLEDs, there is no backlight, and the contrast is very high (black is really black). We picked this display for its excellent color, this is the nicest mini OLED we could find. This guide will show you how to hook it up and use it with an Arduino.
Adafruit currently sells a really cool 16x32 RGB LED matrix panel in their store that is "designed to be driven by an FPGA or other high speed processor." The purpose of this tutorial is to help you get started driving a small handful of these displays with the DE0-Nano board, which contains a mid-range Altera FPGA.
If you want to take your project portable you'll need a battery pack! For beginners, we suggest alkaline batteries, such as the venerable AA or 9V cell, great for making into larger multi-battery packs, easy to find and carry plenty of charge. If you want to go rechargable to save money and avoid waste, NiMH batteries can often replace alkalines. Eventually, however you may want to upgrade to the shiniest new technology - rechargable lithium ion/polymer batteries. In this guide you will learn all about these batteries, and how to properly use them in your projects.
The most important debugging tool in any E.E.'s toolbox is a trusty multimeter. A multimeter can measure continuity, resistance, voltage and sometimes even current, capacitance, temperature, etc. It's a swiss army knife for geeks! This guide will teach you how measure continuity, resistance, and voltage with a multimeter.
A power supply is a device that supplies power to another device, at a specific voltage level, voltage type and current level. While it sounds simple, power supplies have a lot of little hang-ups that can be very tricky for the uninitiated. This tutorial will try to help explain all about power supplies.
Make your projects to go green this summer with our specialized USB/Solar Lithium Ion Polymer Battery charger! This charger is a very unique design, perfect for outdoor projects, or DIY iPod chargers. We've spent over a year testing and tinkering with this charger to come up with a plug and play solution to charging batteries with the sun and we're really pleased with what we ended up with.
