The Art of Micropython- using Python to create award winning art
summary
A 600×600 mixed‑media piece uses four Fibonacci PCB forms, driven by a hobby servo and about 70 NeoPixels, with control split across MicroPython on ESP8266 boards; initial builds burn servos because LED dimming corrupts PWM timing. Synchronization ends up as three GPIO lines (step pulse, direction, reset) plus a potentiometer tap read into ADC so each controller keeps position via servo ADC feedback and a linear regression calibration. After power and homing fixes the installation runs reliably.
