The other day I wanted to experiment with external triggers for my Canon EOS 550D camera. I stumpled upon a nice open source project called Arduino Camera Control from Oleg Mazurov, the creator of the USB Host Shield library for Arduino. The Arduino Camera Control project depends on the USB Host Shield library and the

This program will allow adjust the speed of a blinking LED with analog input. Follow this patch to connect a potentiometer to your Arduino board. Then put an the long lead of an LED in pin 13 of your digital in/out, and the short lead in Ground. /* * AnalogInput * by DojoDave <http://www.0j0.org> *

How does the security alarm circuit works? When power is turned on, the circuit goes into standby mode, and this condition is indicated by “SECURITY ALARM” in the LCD screen.Note that here a N/O reedswitch + bar magnet combination is used to detect any mishaps, and hence the reed switch should be in “closed”state at

A line follower robot using 8051 microcontroller is already published here and this time the same thing is done using arduino. This line follower robot is basically designed to follow a black line on a white surface. Any way the same project can be used to follow the opposite configuration with appropriate changes in the

Introduction Having been a CodeProject member for several years, and not having got round to ever publishing an article, left me feeling a bit disappointed in myself. I have thought many a time on what kind of article I can produce. Then after coming across some great articles by jeffb42 here on CodeProject, my problem

In present time Home/Office and many other place security is most important. In our absence these places are not secure. For make these palaces secure many peoples keep guards and many people prefer electronic security systems. In present time many types of security systems are available in market. These security systems are very accurate and

Arduino Uno is the best development board for beginners in the field of embedded systems. We can program Arduino board with less technical knowledge and programming skills. This tutorial is intended to beginners in the field of Arduino. Hope you already have an Arduino board. Then you have to download Arduino Software and Driver. You can

Analog to digital conversion module of ARDUINO UNO has 6 input ports. The number of the port varies with your ARDUINO model but the coding remains the same. The analog reading in the analog inputs are converted into corresponding 10bit(0-1023). ARDUINO developers have made such an option that you can print anything and see it on the Serial monitor.

In case you don’t have an AVR programmer but you do have an arduino, the arduino can be converted into an AVR flash programmer, meaning it can program bare AVR microcontroller chips. Say if you have an AVR chip and you want to program the chip, so that the program that you’ve written and compiled

In this project, we will show how you can build an ohmmeter using an arduino. An ohmmeter is a device that can measure resistance. Most of the times now, ohmmeters aren’t standalone devices but appear as one of type of measuring device amongst many in a multimeter. An advanced multimeter, today, would have an ohmmeter,
