When designing and building a simple motor controller i used 2 snubber circuits, one to protect the main triac and another one the smooth the communication between the phototriac and the main triac. See schematic below.
When testing the circuit however, no matter if the Microcontroller's pin is high or low, the motor always turns on. I found that when removing C1 the problem did not occur and the circuit perform as it originally was supposed to do.
now that C1 is removed, the phototriac does not have a snubber anymore, but seems to work fine
The questions is: Is removing C1 from the circuit a viable option, or will this cause the circuit to fail in the long run? why does the circuit not work when C1 is placed?
Based upon community feedback (thanks!) & more online research I decided to update the circuit:
Where the resistors are 2W the the capacitors are film.
