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() […]
Rotary Encoder Tutorial with Arduino Code int pulses, A_SIG=0, B_SIG=1; void setup(){ attachInterrupt(0, A_RISE, RISING); attachInterrupt(1, B_RISE, RISING); Serial.begin(115200); }//setup void loop(){ } void A_RISE(){ detachInterrupt(0); A_SIG=1; if(B_SIG==0) pulses++;//moving forward if(B_SIG==1) pulses–;//moving reverse Serial.println(pulses); attachInterrupt(0, A_FALL, FALLING); } void A_FALL(){ detachInterrupt(0); A_SIG=0; For more detail: Rotary Encoder Video Tutorial with Arduino Code
This is a tutorial for using the 7-Key Slider/Wheel Breakout from Rachel’s Electronics. I’ll show you how to solder up the header pins for maximum usability. Rachel’s has the QT1106 datasheet on their site, and a great arduino library for this breakout. The kit from Rachel’s Electronics comes packed with cool stuff: QT1106 breakout with
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
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
Do I need to say more about GPS? See here for some background info: Global Positioning System (GPS) In this tutorial, I will be showing you how to use Arduino, a GPS Arduino shield and a SD card to make a handheld Arduino GPS logger, to record your latitude and longitude over the course of a day.
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
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
Let’s Make It Inaugural Episode – Let’s Make It – Episode 1 This is our very first episode of Let’s Make It. In this episode we introduce ourselves and talk a little about what is coming up. Hint: It is Arduino, Raspberry Pie, PIC Chips, Circuit Design and PC Board Manufacturing. Fun stuff! For the
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
