#312 TheMatrix/Firecracker

A firecracker simulacrum running on the BoldportClub Matrix.

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

Notes

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

Code

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

LEAP is just 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.

Projects are often inspired by things found wild on the net, or ideas from the many great electronics podcasts and YouTube channels. Feel free to borrow liberally, and if you spot any issues do let me know (or send a PR!). See the individual projects for credits where due.

For a while I have also included various scale modelling projects here too, but I've now split those off into a new repository. Check out LittleModelArt if you are looking for the modelling projects!
