Microcontrollers, Software, and You — Part 4

We ended our Part 3 article by giving you an assignment that emulates the card game, often called In Between (but better as known Acey Deucey). Recall that the objective of the game was to have the “dealer” turn two cards face up and then have the player bet that the next card would fall “in between” the two face-up cards. Let’s see how close your code came to mine.

Hacking LEDs and Arduinos: Instant LED Projects

Most LED projects involve some wiring, some resistors, a solderless breadboard, and a bunch of jumper wires. Not this one! You can create bright, stunning colors by literally just plugging LEDs directly into the Arduino pins. No wiring, no resistors. Just your Arduino and a handful of LEDs. The is the absolute simplest and lowest cost way to get started manipulating light and color. I’ll show you how to do it safely in this article.

Microcontrollers, Software, and You — Part 3

While getting the correct answer to a programming problem is crucial when designing a program, it should not be your only objective. You also want to write it with sufficient clarity that someone else can read your code and easily understand what the code does. Let’s take a look at an example program to show the square of a number.

An Introduction to the Parallax Propeller 2

This article gives an easy preview and shows you how some of the neat new features in the long-awaited Propeller 2 can be leveraged in your applications.

The Dr. Duino Explorer — A Review

Stop spending hours fighting your breadboard! With the Dr. Duino Explorer, you’ll save a ton of time on your next Arduino project. Whether you’re a novice or experienced Arduino user, the Explorer offers an array of commonly used sensors and modules with the ability to connect and disconnect what you need at will. It has a novel mechanism for routing digital and analog I/O pins to wherever you need them.

Microcontrollers, Software, and You — Part 2

In the previous installment, we discussed the Five Program Steps and how we can use those five steps to organize our thoughts about writing programs. In this article, we’ll discuss the format that the Arduino Integrated Development Environment (IDE) requires for your program to execute in the IDE. We’ll then examine how the IDE allows us to easily organize a program using the Five Program Steps.

A Real-Time Operating System for the Arduino

An RTOS (Real Time Operating System) is a software component that lets you rapidly switch between different running sections of your code. Think of it as having several loop() functions in an Arduino sketch where they all run at the same time.
