Many times I have Googled for “Arduino Robot” in hopes of finding a robot to build. I end up finding many versions of a obstacle avoiding robot that uses either an infrared or a sonar range finder sensor mounted on a servo to detect objects in its way while randomly roaming the area around it. […]

This project uses just three main components to provide forward and reverse control for a single motor.  You can easily interface it to an Arduino or any other microcontroller. It’s so simple – you can wire it up “free-form” without a circuit board in about 15 minutes. Features: All parts available at Radio Shack for […]

Nokia manufactures a wide variety of cell phones and many of their cheaper phones contain simple LCD’s which may be used in microcontroller projects.  There is one particular LCD model that is used in a wide variety of their phones and is often referred to as simply a “Nokia LCD”, or “Nokia 6100 LCD”.  I […]

Use the Maxim MAX7219 LED display driver with Arduino in Chapter 56 of our Arduino Tutorials. The first chapter is here, the complete series is detailed here. Update – 4/1/15 – This article is pending a re-write, please refrain from comments and questions until the new version is published.  Introduction Sooner or later Arduino enthusiasts and beginners alike will come […]

Ollie is an open source blimp-based autonomous and ambient robot that dwells in human habitats. Ollie is observant, often flying in a manner suggesting curiosity for the world around him. Ollie reacts to voices by excitedly flapping his wings, communicating his friendliness and eagerness to be noticed. Ollie wants to know about humans and yearns […]

Idea: To take one of my old Playstation 1 controllers and extract the dual thumbstick setup so that it can be easily used in a microcontroller project (in my case: with the Arduino) without extra libraries or drivers that you would need if you want to use the entire controller. Please let me know what […]

After buying a Nanode (an Arduino-compatible board with ethernet built-in) last weekend, we’ve been trying to work it out by making a couple of simple examples, the ‘Binary Dice’ is the first one with input and outputs. A note, this code example is based on the one from the book Arduino: A Quick-Start Guide by […]

Make A “doorbell” using an Arduino Uno, a Wave shield from Adafruit, a small speaker, a plug, a Sharp distance sensor and a Shaun the Sheep.  Our Shaun is used in an open doorway to alert store staff when a customer has entered. Step 1: Parts List 1. Wav Shield Party Pack (includes speaker and […]

I came across a bunch of stepper motors and I have since been looking for a project to do with the kids. An old Telecran (French for Etch-a-Sketch) later, we are in business ! What I used for this project: – an Arduino Uno – 2 stepper motors – 2 easydrivers v44 (by www.sparkfun.com) – […]

Instantaneous Voltage and current AC Voltage and current continually alternate, as the name suggests, if we draw a picture of the voltage and current waveform over time, it will look something like the image below (depending on what’s using power – the current waveform – blue in the diagram below – is what you get […]
