At each iteration of the loop, the voltage is read, the GPIO pin is read and the time is noted. I add these values to a python list where I am logging events.
When the callback occurs, I note the time and read the GPIO pin 25. However, the ripple does not go low enough to trigger a falling edge I close the relay, energizing my rectifier and supplying rippling ~ 3.0 v to the GPIO Pin 25. Initialize the GPIO pins and set up GPIO.BOTH edge detection on pin 25 to call my callback routine.
