Hi all, I am looking to hook up a nodemcu to my led driver (meanwell hlg-480-B 3-in-1 dimming fonctions) I have a NPN bc547 transistor from what I've read online this should be enough even tho an octocoupler is recommanded as the safer options. Anyone know how should I wire so that I can send PWM 0-10v signal from an 5v/3.3v nodemcu pwm pin?
