Get flash to fully experience Pearltrees
Update (December 30, 2010) : Latest version of Arduino TinyWebServer: arduino-tinywebserver-20101230.zip . Update (December 8, 2010): The below picture of the required Arduino hardware is obsolete. Look at this newer post for updated information on the new hardware. In part 1 of the Arduino Tiny Web Server I presented some hardware modifications and changes to the Arduino Ethernet shield and the Adafruit Data Logging shield.
Learning Examples | Foundations | Hacking | Links This document explains how to create a library for Arduino. It starts with a sketch for flashing Morse code and explains how to convert its functions into a library. This allows other people to easily use the code that you've written and to easily update it as you improve the library.
Lira – A Barebones, Low-Cost, Arduino Compatible Atmega328 Breakout Board – [ via ] What I came up with is the Lira. It is, as you will see, little more than a breakout board for the ATmega328, but it provides all the bare necessities like voltage regulation, basic power conditioning and an FTDI programming interface.
You can use Arduino with Ethernetshield to fetch temperatures over network. I have created an little sketch for Arduino. This sketch has got an "telnet" server. If you connect to the IP address of the arduino, you will get the temperature from all connected DS1820 sensors. The DS1820 sensor is build in the 6.2 inch female plug. I have only two sensors connected, but you can connect more sensors to the One Wire Bus.
You can not drive a solenoid directly from your Arduino.
The most fun you can have (after blinking LEDs) is using sensors to detect whats going on in the world and act on that information. However, all sensors have their own methods of interfacing. That can make them a real pain to work with: some need pull-up resistors, some need certain power supplies, some use lots of power, some don't.
Reference Language | Libraries | Comparison | Changes Libraries provide extra functionality for use in sketches, e.g. working with hardware or manipulating data. To use a library in a sketch, select it from Sketch > Import Library .
Reference Language | Libraries | Comparison | Changes Looking at the board from the top down, this is an outline of what you will see (parts of the board you might interact with in the course of normal use are highlighted): Starting clockwise from the top center: Analog Reference pin (orange) Digital Ground (light green) Digital Pins 2-13 (green) Digital Pins 0-1/Serial In/Out - TX/RX (dark green) - These pins cannot be used for digital i/o ( digitalRead and digitalWrite ) if you are also using serial communication (e.g. Serial.begin ) .
Removed directly from the arduino.cc website, the only mod, was the pins i chose... the code is attached, instructables won't let me paste it onto here for some reason... The code will print the numbers of they keys you pressed, to the COM port. also, be sure to have the library ''keypad'' in your libraries folder, or this code will not compile. To use similar, but not equal keypads, just grab your continuity tester, and press those buttons, you will easily find wich pins are for the rows, and wich are for the columns.
This was originally written up as an article for issue 159 in Circuit Cellar, and is covered in much greater depth there. You can purchase the article online . There are (millions) of Palm devices out there on the market.
This small library allows developers to remotely read and write data from Arduino projects using simple HTTP requests and JSON responses. Built to work with the AsyncLabs WiShield . This library listens on port 8181 for a command and up to 2 arguments. It generates and sends a JSON response.
