This is a simple low-frequency PWM-write made from nodes of the standard library. I use it for ESP32 because the standard pwm-write node doesn't work. The effective frequency is 100-200 Hz. Duty cycle varies from 16...83%. Also accepts discrete 0s and 1s. I checked the result of the node's operation with an oscilloscope.
