There are easy ways of getting more I/O pins for any project; shift registers, I2C expanders, or ADCs will give you plenty of pins for whatever project you have in mind. All these require extra ...

So if you’re knee deep in an Arduino-based project and you want to constantly monitor all of the micro’s pins, what’s the best way to go about it? [Jonathan Clark] from LVL1 in Louisville was looking ...

An automatic toll gate system using Arduino revolutionises traditional toll collection by eliminating manual intervention.

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

I became aware of the Arduino Project from occasional media reports and a presentation at Atlanta LinuxFest 2009. I was impressed with what the Arduino community was doing, but at that time, I saw no ...

This article will help you build a simple Arduino-based DCC system. Growing up in the 1980s I was living the dream. I had an HO layout on a 4 x 8 sheet of plywood in my parents' basement in Reading, ...

A pulse-width-modulated (PWM) signal and the RC-charging characteristics of a weighted-capacitor network can be used along with a CMOS Schmitt inverter to generate a pulse whose width is linearly ...
