PIFcamp Plant Analyzer
From Hackteria Wiki
Further developed and worked with during the Lab-in-the-Wild @ PIFcamp, Trenta 2015
Intro
It's basically the same circuit as the NanoSmano Sajica aka Vive-la-Resistance. A basic 4093 single oscillator using 1 NAND gate and buffering the output through another gate to control the LED and further buffering it through a gate to be used as output for a piezo or read-out using the freqCount library.
