This uses the M5Stack RCA module and a slightly modified version of the Fire MicrophoneSignalTFT example https://github.com/m5stack/M5Stack/blob/master/examples/Fire/MicrophoneSignalTFT/MicrophoneSignalTFT.ino Combined with the Uncanny Eyes sketch for the M5Stack Core which I found here: https://www.youtube.com/watch?v=zoiuc4Al0EI I am fairly happy with the results, my next step will be to add some type of "AI" or conversion bot to it.
