Hello I'm working on a ESP8266 project using common anode RGB LED's with 100ohms resistors. The problem I'm having is that being that the Esp8266 is on 3.3v the leds are not bright enough. I do have 5v incoming voltage to the ESP8266 with a ams1117 3.3v LDO. So i was wondering if i use a 2N2222 npn transistor's on the RGB led would it be enough?
What i mean is i been searching for the base of the transistor to see if 3.3v max on the esp8266 would fully open the transistor to the max brightness. So i searched online and getting mix confusion on the voltage of the base at it's max what is needed. Can someone please help me out on that.
