Arduino is an open-source computer hardware and software company, project and user community that designs and manufactures kits for building digital devices and interactive objects that can sense and control the physical world. Arduino boards may be purchased preassembled, or as do-it-yourself kits; at the same time, the hardware design information is available for those who would like to assemble an Arduino from scratch. The first Arduino was introduced in 2005. The project leaders sought to provide an inexpensive and easy way for hobbyists, students, and professionals to create devices that interact with their environment using sensors and actuators. History Arduino started in 2005 as a project for students at the Interaction Design Institute Ivrea in Ivrea, Italy. Hardware An official Arduino Uno with descriptions of the I/O locations The Arduino board exposes most of the microcontroller's I/O pins for use by other circuits. Official boards Shields Notes
4051A multiplexer or demultiplexer enables you to expand the in-and outputs on your Arduino board. The 4051 is an 8 channel analog multiplexer / demultiplexer, thus: If you use the 4051 as a Multiplexer: You can choose between 8 different inputs and select just one you want to read at the time.If you use the 4051 as a Demultiplexer you can choose between 8 different outputs and select just one you want to write at the time. Futhermore, the 4051 is able to work with analog values; in the case of the Arduino, you are able to use the analog inputs with a voltage between 0-5V and route them to an Analog-In Pin on your Arduino. To select the Pin we would like to read or write, we have to use the three Select Pins (S0, S1 and S2). If S0 and S1 are HIGH and S2 is LOW pin y3 is selected (1+2+0 = 3).If S0 and S2 is HIGH and S1 LOW pin y5 is selected (1+0+4 = 5). It is not possible to read or write more than one pin on the 4051 at the same time, because you can only select one pin at a time.
Exploring Arduino | Companion Site for the Book by Jeremy BlumIntroductionWhat is Arduino? Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. To do so you use the Arduino programming language (based on Wiring), and the Arduino Software (IDE), based on Processing. Over the years Arduino has been the brain of thousands of projects, from everyday objects to complex scientific instruments. Arduino was born at the Ivrea Interaction Design Institute as an easy tool for fast prototyping, aimed at students without a background in electronics and programming. Why Arduino? Thanks to its simple and accessible user experience, Arduino has been used in thousands of different projects and applications. How do I use Arduino?
Sensing Barometric Pressure | BMP085Light, location, temperature… What’s next? Well, how about Barometric pressure? You know.. that thing that determines so much of our weather. For this example, the way we will be calculating altitude is imprecise and does not compensate for temperature or many other things that can contribute to differences. The reading differs from my weather report Im not going to get into why this is, but to make comparisons easier, your weather report uses a sea-level compensated reading, not an actual reading. Hooking it up Hooking it up to your Arduino is pretty simple, the BMP085 is an I2C device. Code The code for this is largely copied and based off of Jim Lindblom’s example from SparkFun (Thanks Jim!). The code simply outputs the temperature, pressure, and altitude in the serial terminal.
What is an Arduino?Favorited Favorite 14 Introduction Arduino is an open-source platform used for building electronics projects. Arduino consists of both a physical programmable circuit board (often referred to as a microcontroller) and a piece of software, or IDE (Integrated Development Environment) that runs on your computer, used to write and upload computer code to the physical board. The Arduino platform has become quite popular with people just starting out with electronics, and for good reason. This is an Arduino Uno The Uno is one of the more popular boards in the Arduino family and a great choice for beginners. This is a screenshot of the Arduino IDE. Believe it or not, those 10 lines of code are all you need to blink the on-board LED on your Arduino. You Will Learn In this tutorial, we’ll go over the following: What projects can be accomplished using an ArduinoWhat is on the typical Arduino board and whyThe different varieties of Arduino boardsSome useful widgets to use with your Arduino Reset Button
untitledTemperature Measurment using the Dallas DS18B20 copyright, Peter H Anderson, Baltimore, MD, May 6, '07 Introduction Note that this is my first venture using the Arduino and I am amazed with the possibilities. I used and a FTDI TTL-232R USB-to-TTL serial cable. This program continually measures the temperature at three points using the Dallas DS18B20 1-W thermometer. My plan is to extend this to illustrate how to interface with the DS2438 battery monitor to measure a voltage and a temperature, the DS2423 which has two 32 bit counters and the DS2450 quad A/D converter. I realize there is a library of OneWire routines. Detailed Discussion. Each transmission is initiated with a reset (or presence) pulse, by bringing the signal lead low for 500 us and then back to high-Z for 500 us. The commands 0xcc (skip ROM) followed by 0x44 (perform temperature measurement) are written to the device. This is followed by the reset pulse and commands 0xcc (skip ROM) and 0xbe (read temperature).
BoardUnoOSH: Schematics, Reference Design, Board size Arduino / Genuino Uno is open-source hardware! You can build your own board using the follwing files: Programming The Arduino/Genuino Uno can be programmed with the (Arduino Software (IDE)). The ATmega328 on the Arduino/Genuino Uno comes preprogrammed with a bootloader that allows you to upload new code to it without the use of an external hardware programmer. You can also bypass the bootloader and program the microcontroller through the ICSP (In-Circuit Serial Programming) header using Arduino ISP or similar; see these instructions for details. The ATmega16U2 (or 8U2 in the rev1 and rev2 boards) firmware source code is available in the Arduino repository. Warnings The Arduino/Genuino Uno has a resettable polyfuse that protects your computer's USB ports from shorts and overcurrent. Differences with other boards The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Power Memory PIN MAPPING ATmega328P
How To Make The Easiest Breadboard Arduino Uno...EVER ! - The Breduino ! (& How to Upload Sketches Straight to it !!) With Additional Hardware Options - UPDATED - 2013Okay now before i start, something about my notes for my step-by-step PICTURE instructables that i Love to create: "i used to label all my pictures within my instructables but it seems instructables.com doesn't show all the notes attached onto pictures with certain web-browsers so i will be only making a few notes Directly onto the Pictures but have the main instructions here in this typed section but for those of you that dont see any notes on the pictures either download and install another web-browser (i Use Opera and have Never had a Problem Seeing Notes on Pictures!) or just look at the notes in this typed-section of the Instructable Guide i have made !! Now, start by chopping up some single-core wire into the different lengths (or just chop them as-you-go!) The Power Supply: Also i used a bit of Green Single-Core wire & its not in the first 3 pictures but you will easily spot it when its used (For the Tactile MicroSwitch!) Now we finally start the Power Supply, lol ! DONE !!!
