Hi all, I have been thinking about this project for some time and know that I lack the experience in a key area regarding AC voltage.
I have several sets of christmas lights that I put up around windows and doors on the front of my house that are multicolor/multifunction lights. What I would like to do is synchronize those sets of lights. I have already used wireless comms for Halloween decorations so have a basic idea of how to achieve what i want.
The problem for me is that the lights are controlled by a small microcontroller chip that fades/flashes each color strand according to the multi function program. I have measured and each strand was running about 33 volts AC if I recall at full brightness.
My idea is to measure the AC voltage of each strand, transmit that wirelessly to controllers at the other strands and reproduce the color/brightness levels.
I just have no idea how to measure AC voltage or achieve that goal. The only other thought I have had on this would be to measure the voltage at the transistor PIN controlling the lights power voltage. I just don't know how to do that as its all AC power.
Thanks for any thoughts/insight.
