I enjoy using my Mini Maestro 12 Channel Servo Controller; and am wondering if there is a way to dim AC lights through a channel set to output. In a previous experiment, this servo controller was able to turn on and off a relay module when they were both connected to the same 5 volt power source and their signal lines were linked. I tried to duplicate this experiment with a RobotDyn AC Light Dimmer Module, but was only able to turn the light on and off with the servo controller (no dimming). The dimmer module has four ports: VCC, GND, Z-C (Zero-Cross), PWM; and also operates off of 5 volts. Again, I connected the VCC and GND ports to the same 5 volt power supply as the servo controller; and linked the PWM port to the signal line on Channel 8, which I defined as an Output. The one port that I am unsure of where to connect the servo controller to is the Z-C. Is there a better way that I can connect this dimmer module to the servo controller in order to achieve some level of AC dimming? Thank you for your help in advance!
