Teensy USB Development Board. The Teensy is a complete USB-based microcontroller development system, in a very small footprint, capable of implementing many types of projects. All programming is done via the USB port. No special programmer is needed, only a standard "Mini-B" USB cable and a PC or Macintosh with a USB port. Update: Discussion / Support Forum Teensy 3.1 changes from Teensy 3.0 Teensy Loader Application Software Development Tools WinAVR C compiler. Teensyduino, add-on for Arduino IDE. Simplified USB Examples or Dean Camera's LUFA library. Breadboard Usage The Teensy is available with header pins, for direct no-soldering-required use on a breadboard, which can also be run from the +5 volt from the USB cable. The 128x64 Graphics LCD can be used with Teensy 2.0 and Teensy++ 2.0 and Teensyduino using this GLCD library.
Serial Peripheral Interface Bus. SPI bus: single master and single slave Interface[edit] The MOSI/MISO convention requires that SDI on the master be connected to SDO on the slave, and vice versa. Chip select polarity is rarely active high, although some notations (such as SS or CS instead of nSS or nCS) suggest otherwise. SPI port pin names for particular IC products may differ from those depicted in these illustrations. The master does not use an addressing concept while communicating with the slave. Operation[edit] The SPI bus can operate with a single master device and with one or more slave devices.
If a single slave device is used, the SS pin may be fixed to logic low if the slave permits it. Most slave devices have tri-state outputs so their MISO signal becomes high impedance (logically disconnected) when the device is not selected. Data transmission[edit] To begin a communication, the bus master first configures the clock, using a frequency less than or equal to the maximum frequency the slave device supports.
Programming an ATtiny w/ Arduino. This tutorial shows you how to program an ATtiny45 or ATtiny85 microcontroller using the Arduino software and hardware. The ATtiny45 and ATtiny85 are small (8-leg), cheap ($2-3) microcontrollers that are convenient for running simple programs. This tutorial is obsolete! See the updated version of this tutorial (with support for Arduino 1.0).
They are almost identical, except that the ATtiny85 has twice the memory of the ATtiny45 and can therefore hold more complex programs. We like to use both of them with paper circuits and other craft electronics. Materials and Tools For this tutorial, you’ll need: Arduino Uno or Duemilanove (w/ an ATmega328, not an older board with an ATmega168) ATtiny45 or ATtiny85 (8-pin DIP package) a 10 uF capacitor (e.g. from Sparkfun or from Digi-Key ) a breadboard jumper wires For more information, see our list of materials and parts and our list of prototyping supplies .

Mixed Signal Oscilloscope - iMSO-104 | Oscium. Online : Circuit Skills: Perfboard Prototyping, sponsored by Jameco Electronics. [Note: Jameco is currently offering all the parts I used in this video as a perfboard prototyping kit -- just add wire & solder. ] When you think “DIY electronics,” one of the first images that likely comes to mind is of parts and wire soldered to a standard piece of perforated circuit board — and that makes sense.
Perfboard is widely used because it’s so versatile. Essentially, it’s just a grid of potential solder-point connections. You can trim it down to just the size you need, or leave extra space for future enhancements, or revisions, if need be. Subscribe to the MAKE Podcast in iTunes, download the m4v video directly, or watch it on YouTube. In this latest installment of the Circuit Skills video series, I demo my own approach to perfboarding by building a rather unusual guitar effect — the PWM, a design I found in Tim Escobedo’s excellent Circuit Snippets collection. (For those interested, I also drew up a more traditional version of the schematic – available here.)

So about a year ago I decided that I wanted to get into AVR microcontrollers. After ordering an AVR pocket programmer from Sparkfun , I soon realized that it was too delicate to be sitting on a workbench full of wire clippings. I knew I needed a small enclosure to put it in, but couldn't find anything I really liked. My final decision was to make my own. This instructable will explain the steps necessary to construct a "Lexan" shell for an arduino UNO (or other arduino). Of course these steps can be adapted to almost anything. I don't remember where I learned this method, but it was definitely from another Instructable.
Here are some with similar methods: - - -
