Hi everyone,
I am planning to build a midi usb sequencer and I want to use 16x WS2812b LED's as indicators.
Since a single usb can only supply up to 500mA, the LED will have a low brightness so that the total device should need around 400mA.
To power the Teensy and LED's (and getting data), I am thinking to use a y-cable where the data+power connections will go from PC to Teensy and then to use the power-only connection to feed current to the LED's.
Could something like this work? Because I'm not sure if the LED's will get power in this way.
Thanks in advance.
