LEAP#276: Variable Speed Runway LEDs (inspired by the Pease)

in the vein of “now I have a hammer, everything looks like a nail” …I found a new application of the LM331! I was introduced to the LM331 when I built the Pease project. I wanted to drive some variable-frequency LED effects without taxing the MCU. Many ways of doing this, but my solution uses the LM331. This is just a small part of a larger project (hence my desire for no processor overhead). My full build notes are in the LittleArduinoProjects repo. Sneak peek:
