In this week’s arduino tutorial, we take a bit of a detour and focus on some key elements of electrical engineering design that we’ll be using in future episodes. Included amongst these topics is Ohm’s Law, current-limiting resistors, pull-down and pull-up resistors, voltage dividers, potentiometers, analog inputs, and voltage regulators. If you’re yearning to learn

This week, we’ll finally be using the Arduino to control some motors! First up, we’ll control a standard DC motor running off a 9V battery with the help of an NPN transistor and a PWM (Pulse Width Modulated) signal from the Arduino. Next, it’s onto 180 degree servo motors, which we will power on
Arduino Motors and Transistors Continue Reading
As promised, this week brings another communications tutorial! In this video, we’ll use both the serial and processing knowledge that we gained last week, plus an I2C enabled temperature-sensing IC. We’ll use processing to generate a pretty room temperature display on your computer screen. If you are new to processing, they have an excellent

Update (6/7/2012) – I’ve had to disable comments on this post, because it is being targeted by spam bots for some reason. Please use the contact page if you have a question about this topic. In this week’s arduino tutorial, we’ll be taking a look at SPI device control using the arduino. Specifically, we’re going

This project is an update of my original Peak Power Tracker Battery Charger Project. It is designed to control a 12V solar panel charging a 12V lead acid battery. The updated version of this project uses the Arduino Duemilanove development board (from www.sparkfun.com) as the basis for the project. Then I used the Arduino Protoshield

Interrupts are an extremely useful, yet often feared element of microprocessors. Interrupts allow you to run a program, while still being able to react to asynchronous input from the outside world. On many platforms they can be confusing to implement, but the arduino makes it easy! In this week’s episode, I’ll show you how to use

This was easily the most time I’ve spent producing an Arduino Tutorial. I’ve been sporadically walking around NYC with this Arduino GPS for weeks as I’ve tweaked the code and gotten it just right. If it wasn’t obvious from the title, this tutorial will teach you how to use an arduino paired with a GPS Module

To Learn about the basic LED usage practice, read here. What is a RGB LED? With an RGB (Red Green Blue) LED you’ll be able to produce any colour that is flashing everyone’s eyes. At first glance, RGB LEDs look just like regular LEDs, however, inside the usual LED package, there are actually three LEDs, one red, one

Arduino Quadruped Robot – Stalker I am going to build an Arduino Quadruped Robot. As usual, I will share my source code and show as many pictures as possible, to help those of you who are also building Quadruped robots. The way I do things might not be the best ways, and I am sure you can

I had initially planned to do an LCD tutorial a little further down the line, but there was very high demand for it, and I already had a circuit assembled for testing the new LCD that element14 sent me to evaluate. So, this seemed like an appropriate time to roll it out! In this episode,
