I am doing a project for my master thesis and I have 6 stripes of WS2812B LEDs each one containing 77 LEDs. I finished the design and now want to turn them on.
I used an old power supply to power it, but now that I am running it, doesn't work. I checked the voltage with a multimeter and it shows that I have 5 volts and it seems doesn't have any problem but the data doesn't transfer to my strip.
I just copy past FastLED from libraries and changed the number of LEDs. I thought maybe I am using the Funduino from school, maybe this is a problem and I need another Arduino board?
