#312 TheMatrix/Firecracker

A firecracker simulacrum running on the BoldportClub Matrix.

Here’s a quick video showing it in action..



I was a bit dubious about the possibility of creating a decent firecracker animation on the 24x5 Matrix display. The additional PWM settings create another dimension, so the simulacrum is perhaps not so far off the mark.

To light the firecracker, I want to use a real fire of course;-) Exposing the LM35 to a naked flame is perhaps not such a good idea .. but it is only for a moment - enough to take the temp over 35°C


The Firecracker.ino sketch instantiates “Sparklies” which represent individual animation elements.

Doxygen source documentation is available here.

LEAP is my personal collection of electronics projects, usually involving an Arduino or other microprocessor in one way or another. Some are full-blown projects, while many are trivial breadboard experiments, intended to learn and explore something interesting (IMHO!).

The projects are usually inspired by things found wild on the net, or ideas from the sources such as:

Feel free to borrow liberally, and if you spot any issues do let me know. See the individual projects for credits where due. There are even now a few projects contributed by others - send your own over in a pull request if you would also like to add to this collection.
