I tried connecting 8 x ws2812b strips of 50cm length to an umbrella in parallel, somehow it didnt work. The IN of the led strips are at the top of the umbrella, all are connected parallel from this top part. The strips light up but the code of rainbow animation using fastled doesnt work, just frozen.
Im using an Arduino Nano, powering them from a powerbank (works for up to 5meter single strip). I used a single 470ohm resistor for all 8 strips for data line. Im tempted to solder 8 x 470ohm resistors to all data lines but its a lot of work with little chance of that being the issue… I guess asking here seemed a better idea…
I had noticed in previous experiments with lpd8806 strips that if I run through a single strip initially then I can create parallel outs off from the end of this strip and all ran fine. So I tried that again, running a single ws2812b to the top and then connecting all the strips to the out of this single one… aaand it didnt work.
Anyone know what the problem might be?
