Description

I was inspired by the the electronic sculptures of Gislain Benoit and a local artist who&apos;s turning old instrument parts into animated bug sculptures.<br>The back of the bug is touch-sensitive and triggers flashes of light when touched.<br>An old phone speaker provides a heavy base and produces random crackling sounds when the leds are flashing, giving even more life to this critter.<br><br>This was also a good introduction to FreeRTOS.The Leds and speaker are driven by their own FreeRTOS Task and an EventGroup is used for inter-task communication and state management.<br>The tail of the &quot;AVR Bug&quot; is an ICSP connector for easy re-programming. <br><br>Video demo available here:  <a target="_blank" rel="noopener noreferrer" href="https://www.youtube.com/watch?v=ybKKlLko81M">https://www.youtube.com/watch?v=ybKKlLko81M</a><br>The source code is available on my GitHub:  <a target="_blank" rel="noopener noreferrer" href="https://github.com/Pat">https://github.com/Pat</a>
