Introduction

The following article is about my simplest library that I wrote for the arduino: SoftTimers. The SoftTimers arduino library allows one to properly time multiple events and know when each “timer” expires meaning that an action is required.

When I first learned programming the arduino, I learned the “hello world” of the arduino: turning a LED on and off. As expected, I used delay() to define how long the LED should be on and off.

Introduction

The following article is about yet another Arduino library that I have written. AnyRtttl is a feature rich arduino library for playing RTTTL melodies. The library offers much more interesting features than relying on the widely available void play_rtttl(char *p) function. The AnyRtttl is a feature rich library which supports all best RTTTL features.

Purpose

See this post for a quick recall of the RTTTL format.

Introduction

Please note that win32Arduino source code is now moved to GitHub. Source code can be downloaded from the project’s GitHub page.

After implementing many arduino library, I realized that unit testing a library is harder than I though. Most of the time, the library does not even require advanced arduino functionalities and could be tested outside of the arduino platform.

The win32Arduino is a solution to this issue.

Introduction

The following arduino library was written to use the findings found during the Mapping RC Transmitter PWM signal to actual transmitter values article. All results were wrapped into a library for ease of use.

The RcReceiverSignal is an arduino library that allows one to read a signal sent from a Remote Controlled (RC) receiver.

Purpose

The RcReceiverSignal library allows one to easily configure an input pin to read a PWM signal sent from a RC receiver by attaching a RcReceiverSignal instance to a pin connected the receiver and automatically monitor each pulse sent by the receiver.

Introduction

Here is another arduino library that I have written.

As a desktop developer, I am not used to have memory (or even CPU) requirements as most developers will not look at memory consumption as an arduino developer would. Memory & CPU is cheap. If your application is struggling to run on today’s computer, it will run smoothly in 1-2 years.

As most arduino developers have faced, the amount of memory available on embedded devices is pretty limited. Having a way to save bits or our precious memory is interesting.

Introduction

The following article is about my first Arduino library that I have written. NonBlockingRTTTL is a non-blocking arduino library for playing RTTTL data.

EDIT: The NonBlockingRtttl arduino library is now moved to GitHub. Source code can be downloaded from the project’s GitHub page.

EDIT: NonBlockingRTTTL library is now available on the Arduino Library Manager.

Purpose

Most code that can be found on the internet that allows you to “play” an RTTTL string is build the same way: sequential calls to the tone() function followed by a delay() function. This type of implementation might be good for robots but not for realtime application or projects that needs to monitor pins while the song is playing.
