I have a task though it sounds simple i am not getting enough insight on how to get it sorted!
So basically i am design a GUI Program that will "Dim" a 240 LED bulb. yeah simple as that hun?
while the program communicates with Atmega328p via bluetooth uart and can accept the dimming command
i am not clearly seeing what part / parts / IC/ etc... that i will use to control 240V 10A from MCU point of view!
I have used MCP Digital Potentiometer before and it was the nearest thing in my mind to vary the output voltage automatically
but also PWM approach is possible. the only hindrance i have is the dimming communication between the TTL lever of MCU and 240V of the Lamp.
and thought or techniques here are very much appreciated.
