Raspberry PI. Programming an ATtiny w/ Arduino 1.0. This tutorial shows you how to program an ATtiny45, ATtiny85, ATtiny44 or ATtiny84 microcontroller using the Arduino software. These are small, cheap ($2-3) microcontrollers that are convenient for running simple programs. The ATtiny45 and ATtiny85 have eight legs and are almost identical, except that the ATtiny85 has twice the memory of the ATtiny45 and can therefore hold more complex programs. The ATtiny44 and ATtiny84 have 14-legs and more inputs and outputs. Thanks to Mark Sproul for his work on making the Arduino core portable across processors. ATtiny45/85 vs. an Arduino Board The ATtiny45 or 85 is a great option for running simple Arduino programs: it’s small, cheap and relatively easy to use. In short, then, if your project requires only a few simple inputs and/or outputs, you’re probably fine using an ATtiny.
Materials and Tools For this tutorial, you’ll need: An in-system programmer (ISP), a piece of hardware used to load programs onto the ATtiny. Connecting the ATtiny Reference.

We've done a lot so far, blinking lights, printing messages...all of that stuff is output: signals coming from the Arduino. The next step is to start playing with input, with the Arduino responding to outside events. In this lesson we will begin with the most basic kind of input, a push-button switch! You're probably familiar with switches, there's tons of them in your house.
One kind of switch you use every day is a light switch. On the left, the switch is open and no current flows. (thanks wikipedia!) In this photo, you can see the internals of a light switch. Light switches are great but we need something smaller. These little switches are a 1/4" on each side, cost about 25 cents, and can plug directly into a breadboard. Normally, the two wires are disconnected (normally open) but when you press the little button on top, they are mechanically connected. Find 5 things around the house that have switches.
Power up the Arduino and try pressing the button. Switch capability Fig 5.2 Fig 5.4. Arduino - HomePage.

Watchdog and Sleep functions This example shows how to make use of the Watchdog and Sleep functions provided by the ATMEGA 168 chip . These functions are useful if you want to build low power consuming devices operated by battery or solar power. The reduced power consumption is achieved by through a intermittent operation of the system .In case of Arduino your main loop will be executed once before the system is put into the sleep mode. After a few seconds t the watchdog wakes the system up and the main loop is executed again. When we assume that the time to measure a sensor and making some decisions will take 10 millisecond and the watchdog is set to 8 seconds the on/off ratio is 800 which extends the battery live time by this factor.
Battery live time calculation Now we want to know long we can operate our device with standard alkaline AA Cells. In normal operation with a current of 20mA the battery will last 2000/20 = 100 hours or about 4 days. Nightingale Example Burn the Bootloader. /arduino/ - gfb - Random garblings.
