Windows 1 | Get an Arduino board and USB cable In this tutorial, we assume you're using an Arduino Uno, Arduino Duemilanove, Nano, Arduino Mega 2560 , or Diecimila. If you have another board, read the corresponding page in this getting started guide. You also need a standard USB cable (A plug to B plug): the kind you would connect to a USB printer, for example. 2 | Download the Arduino environment Get the latest version from the download page. When the download finishes, unzip the downloaded file. 3 | Connect the board The Arduino Uno, Mega, Duemilanove and Arduino Nano automatically draw power from either the USB connection to the computer or an external power supply. Connect the Arduino board to your computer using the USB cable. 4 | Install the drivers Installing drivers for the Arduino Uno or Arduino Mega 2560 with Windows7, Vista, or XP: Plug in your board and wait for Windows to begin it's driver installation process. See also: step-by-step screenshots for installing the Uno under Windows XP.

Detail pin out of several device Liquidware : Open Source Electronics Weather Station Receiver The incredible popularity of home weather stations shows that it's not just farmers who are interested in the weather. Many people want to be able to track and record weather events within their local environment rather than relying on a state or national weather service that may not have adequate local details. Home weather stations typically consist of two major parts: the sensors that sit outside and measure temperature, wind speed and direction, humidity, rainfall, and barometric pressure; and the display unit that lives inside in a convenient place so you can read the external temperature while sitting around the fire warming your feet and deciding whether it's too cold to go fishing. Generally the external sensors connect together with cables with one sensor also acting as a transmitter to send updates wirelessly to the display unit.

Electronics - News ArduinoBoardDuemilanove Overview The Arduino Duemilanove ("2009") is a microcontroller board based on the ATmega168 (datasheet) or ATmega328 (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. "Duemilanove" means 2009 in Italian and is named after the year of its release. Summary Schematic & Reference Design EAGLE files: arduino-duemilanove-reference-design.zip Schematic: arduino-duemilanove-schematic.pdf Power The Arduino Duemilanove can be powered via the USB connection or with an external power supply. External (non-USB) power can come either from an AC-to-DC adapter (wall-wart) or battery. The board can operate on an external supply of 6 to 20 volts. The power pins are as follows: VIN. Memory The ATmega168 has 16 KB of flash memory for storing code (of which 2 KB is used for the bootloader); the ATmega328 has 32 KB, (also with 2 KB used for the bootloader). AREF.

Tutorial: Arduino and Push-wheel switches - Birds on the Wire Welcome back fellow arduidans! In this article we go back to the past via the use of push-wheel/thumb-wheel switches with out Arduino systems. Here are some examples sourced from somewhere on eBay: For the uninitiated, each switch is one vertical segment and they can be connected together to form various sizes. The switch’s value is made available via binary-coded decimal. We have common on the left, then contacts for 1, 2, 4 and 8. By now you should realise that it would be easy to read the value of a switch – and you’re right, it is. From a hardware perspective, we need to take into account one more thing – the push-wheel switch behaves electrically like four normally-open push buttons. Now it is a simple matter to connect the outputs labelled 1, 2, 4, and 8 to (for example) digital pins 8, 9, 10 and 11. Example 40.1 The function readSwitch() is the key. Ok it doesn’t look like much, but if you need numerical entry it saves a lot of physical space and offers a precise method of entry.
