Hi, I found this instructable https://www.instructables.com/id/Multichannel-Wireless-Light-Dimmer/ with a circuit for a trailing edge dimmer. I would like to replicate it but instead of two channels I would like to go for 12.
I understood all the working principle, but since I will have 12 channels I would like to optimize a little.
This is the original schematic. https://cdn.instructables.com/ORIG/FP6/5RF8/J2MAORX6/FP65RF8J2MAORX6.pdf
In the instructable description the author states that each channel must have its own 12V supply to trigger the mosfets.
I can't understand why.
Is there a way to have a single 12 or something volts (the mosfets I plan to use hame max Vgs of 25V) supply for all of them?
