    Arduino tutorial  

    Should I Upgrade to the latest Arduino IDE? If you have been working with Arduino you may notice a small popup that tells you about a new update for Arduino IDE. You may wonder if there are problems with getting the latest software because as you know its old systems may not work with the new software. Recently an update came out for Arduino IDE 1.6.1. This version has...
    Digital Potentiometer Arduino Shield One step ahead: in this article we will review the project for an Arduino shield compatible with Arduino Duemilanove, Diecimila and Arduino UNO R1 and R2. This shield is based on AD5206 digital potentiometer. We can find some very basic applications of the component reviewed in many blogs and sites, including the arduino.cc...
    ICSP custom cables and Arduino As soon as we start getting familiar with the basics of Arduino, we start noticing some interesting components that are not commonly used on the Arduino. One of these things are the ICSP headers. They are those six pins that stick out, organized in a two-row three-column orientation. As Arduino enthusiasts become familiar with...
    Arduino RFID Reader RC522 + Access Control System I just received my RC522 RFID reader and made this simple Arduino access control system that uses the reader, a buzzer for the alarm and a relay shield for the security system. The relay can be used to open a door lock and if you need a louder alarm then you can replace the small buzzer with a high power siren. I will not talk...
    Arduino DHT22 (AM2302) Tutorial + Library You can use the DHT22 (or AM2302) humidity/temperature sensor and the Arduino UNO board to read data and print it out to the serial monitor or to display it on an LCD. In my case I chose the serial monitor version because is faster and cheaper, but you may want to look at other articles, including this one, if you want to use...
    Multiple Shift-out Registers on Arduino – part 2 In this second article we will see a practical application of the daisy-chained shift registers. We want to use four 7-Segments LEDs controlled by the Arduino board. As you can imagine, that is impossible without a series of shift-registers as we need 32 output pins. As we can do in many other applications of the daisy-chained...
    Multiple Shift-out Registers on Arduino – part 1 Shift-out: again? Yes, shift-out registers again, now daisy-chained! But let me write down a short foreword. As probably occurs for most of the subjects, especially those related to the Arduino board, shift registers have already been discussed several times on the Internet; Blogs, Sites, Tutorials, Instructables, the same...
    Alphanumeric LCD with Shift Register on Arduino – part 2 As promised in the first part of this article, now it is time to see in detail how we can use the Alphanumeric LCD Display in our Arduino sketches. The idea beside this project is to give a simple output empowering the Arduino board behavior without compromising the sketch space. While the Alphanumeric LCD project for Arduino...
    Alphanumeric LCD with Shift Register on Arduino – part 1 One of the limitations of the small 8 bit microcontrollers like the Atmel ATMega family adopted by the Arduino board, is the reduced number of I/O ports. Among the main advantages of these microcontrollers: they are cheap, robust and simple to program. Therefore, also Arduino or one of its clones are cheap as well....
    Cheap OLED Displays and Arduino We all like cheap items off eBay especially if they do cool and unusual things, sometimes we get so carried away by the price that we do not even realize that fact that we do not know anything about making the product work. A while back, I was browsing through eBay dreaming of all the stuff I can buy if I become rich. Then I...
