PCA9685 Shield - Electroluminicent wire shield (2018) :

This shield is an add-on to the PCA9685 PWM module, (a pwm expansor for arduino).
The shield adds a low pass filter to all outputs which allows Electrolumincet wire 
drivers to be controlled by arduino.
The circuit and boards were desgined and produced  pecifically for my <Cosmological Configuration> installation.
