I want the ability to add more than the standard 3 LEDs to the sleeve of the pioreactor. How would i be able to assign these LEDs to certain GPIOs of the HAT/RPI?
Hi @farascapra, you can place LEDs in series, too. Example:
HAT’s LED channel positive terminal → First LED → Second LED → HAT’s LED channel negative terminal
However, the max current is still limited to 100 mA per LED channel. Are you looking for more intensity (light output) than the existing channels?
