Hi!
Cannot seem to get this going right.
Individually the led strips work, but when I Connect them together as the attached picture I get a lot of flickering on Lights 2.
Is something wrong here?
All grounds splice together and put fuses on each power supply.
@srg74 the GND froim the upper trafo needs to put together with the Trafo on the lower sketch
AND use a FUSE like the one in the Car system you can get it almost on every Fuel supply station
to shield the system
use at least 60-100ohm on the esp32 to the DATA pins to avoid backpower
You will lose the fist and the last LED in stripe if you go direct from pin to Data
As per @srg74,
Common ground for all supplies and strips.
Fuses for power.
Don’t worry about resistors until you’ve solved your power issues.
