Arduino Timer and Interrupt Tutorial

Arduino Timer and Interrupt Tutorial This tutorial shows the use of timers and interrupts for Arduino boards. As Arduino programmer you have probably used timers and interrupts without even knowing it’s there, because all the low level hardware stuff is hidden by the Arduino API. Many Arduino functions uses timers, for example the time functions: delay(), millis() and micros(), the PWM functions analogWrite ...

Arduino I/O-Matlab basic tutorial

this is my very first instructables and I was referred by an old member. Follow her link here: (http://www.instructables.com/member/Analogue-Chick/) Its a simple illustration on how we can connect Arduino to Matlab and actually control and get information on Arduino using Matlab I have seen few tutorials regarding how to control or get data from Arduino using Matlab. Matlab is a very powerful tool for stude ...

Arduino Wireless SD Shield Tutorial

As the name implies, the Arduino Wireless SD shield serves two functions. Foremost, this shield allows you to easily interface with Xbee transceiver modules to create mesh networks, and other wireless devices. Secondly, the micro SD socket allows you to store and access a large amount of data. Whether using these functions by on their own or together, this chip greatly enhances the capabilities of a standar ...

Amicus18: Arduino-style platform for PIC fans

Arduino needs no introduction; it is an easy-to-use yet powerful open source embedded system development platform that has gained huge amount of popularity in past few years, specially among hobbyists. The standard hardware consists of an 8-bit Atmel AVR processor with on-board headers providing access to its I/O pins. The processor is pre-programmed with a serial bootloader that simplifies the uploading of ...

Learn Counter ICs Using an Arduino

Have you ever needed to count something? Sure, we all need to count change, count blessings, and occasionally count cards, but that's not really the kind of counting I'm talking about. In this Instructable, I will elucidate how Counting ICs operate, and show how to connect one to a microcontroller so you can see exactly how it works in a controlled way. Step 1: Why Use Counting ICs? Yes, yes, why not just u ...

Simplified Electric Imp to Arduino Due Tutorial

Introduction: This is a basic tutorial to send information from the Electric Imp to the Arduino Due through UART (RX, TX) I am pretty new to both so some things I write may be incorrect. Most of the information I got from https://www.sparkfun.com/tutorials/397 If you know how to program well that tutorial may be way better then this one, but I thought this would be a more basic and easier tutorial for peopl ...
