NeoPixel LED Analog Clock – Part 2 – Software Implementation

Clock_Art_IconIn Part 1 I described the hardware components and the functionality of the LED clock. This this part, I’ll explore the software required to implement the functionality and seamlessly manage the different user interfaces.

NeoPixel LED Analog Clock – Part 1 – Hardware and Specifications

Clock_Art_IconI wanted a create a simple project to test a few ideas and still be useful in its own right. Walking through my local IKEA store, I saw a really inexpensive analog clock (Rusch) and decided that it would provide the right vehicle for what I had in mind.

Processing Selections from Multiple User Input Sources

MUI_HeaderIn the last few projects I completed, I needed to find a way to process user commands arising from multiple input sources. A simple example would be a clock with tact switches and a Bluetooth interface providing identical functionality from either user input source.

For these applications I developed a simple modular and scalable approach that can be applied in other projects.

Reliable Bluetooth Comms Between Arduino and MIT App Inventor (AI2)

MIT_AI2_IconI recently needed to develop a Bluetooth application between an Arduino and a controlling App running on Android. App Inventor 2 was used to simplify development of the Android App .

MIT App Inventor (AI2) is a web-based online graphical mobile application development environment for Android devices, where you can create an application by simply dragging and connecting a series of function blocks.

When researching the task, I found a lot of disparate information about how to write the Bluetooth management code for AI2. This information (some good, some wrong, and a lot repetitive) was synthesized it into a set of functions, described here, that provide a reliable communications interface to my project.
