A question on the Arduino forum and the thread that followed prompted me to try and emulate a mechanical push- or thumb-wheel display update on an LCD module. The technique uses the LCD programmable characters and could be extended to other applications for simple LCD module animations.
I was exploring ways to make a future robot project more appealing and came across a number of articles about animated robotic eyes created to convey expression or mood. This looked like a bit of fun and quite achievable using the LED matrix modules that I have been playing with for a while. Here’s the result.
Vertical LED dot displays are not a common requirement, but they can be created using the standard library with a few tweaks to the software.
As I get questions about vertical displays from time to time, I will cover the basic process of how this is done in this short article. Continue reading “Parola A to Z – Vertical Displays”
A very powerful feature of the Parola library is the ability to separate a display into a number of zones. This allows the implementation of sophisticated animations schemes and is a key part of being able to create double height displays.
This post explains what they are, how they are set up, and how to manage them.
As the main function of the Parola library is to enable text animations, it is important to understand how these are set up and managed to completion from user code.
From a user perspective, Parola animation consist of 3 parts – setting up, running and resetting the animation. The process is not complex and is illustrated in the numerous library examples. This article breaks these down and explains how the Parola class methods apply in each phase.
The key function of the Parola library is to display text using different animations. These animations are built around a core supporting framework and largely follow the same patterns. This article explores how Parola animations code is constructed so that advanced users of the library have enough information to be able to write (and contribute!) their own new animations.
