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.
There’s no question that we’re fans of the Arduino here at GeekDad ; however, that doesn’t mean we don’t occasionally dabble with other micro-controllers. The Texas Instruments MSP430 Launchpad Kit is a particularly compelling alternative that I’ve been tinkering with lately. And, yes, that price listed above is correct — the Launchpad kit is only $4.30 from TI , making this a very inexpensive way to get started with hardware tinkering.
SPI and ShiftOut()
SPI bus: single master and single slave The Serial Peripheral Interface Bus or SPI (pronounced as either ess-pee-eye or spy [ citation needed ] ) bus is a synchronous serial data link standard, named by Motorola , that operates in full duplex mode. Devices communicate in master/slave mode where the master device initiates the data frame .
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 This tutorial is obsolete!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).
Ever since I started making projects with the Arduino , I’ve had a desire to shrink them down to a single, small circuit board. One of my first projects, a customizable SLR intervalometer , was packed in a phonebook-sized cardboard box and used the Arduino Deumilanove connected to a breadboard with jumper wires. I brought the box out to Central Park at 5am to make a timelapse of the sunrise, but when I got to the park, I spent 20 minutes fixing the connections between the Arduino, the breadboard, and the components. Since then, I’ve explored a few different ways of shrinking projects down and making them more robust. For the intervalometer, I designed a circuit board that had female header pins to seat an Arduino Nano .
“So how does this touch interface compare to an oscilloscope with knobs? We actually think the experience is better! The touch-interface of the iPad represents a viable alternative to traditional knob-based oscilloscopes. The software on this device is outstanding… ” Joe Wolin EEWeb Co-Founder "This is really rather tasty.
[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.
