arduino leds in parallel switched with NPN transistors


Posted on Feb 5, 2014

Just a nitpick, you don`t have the Leds in Parallel with the transistor. If you did, the leds would be on when the transistor is off. You have them in parallel going into the transistor. All the transistor sees is n times led current going through it. It doesn`t know if you have 5 20mA leds in parallel or one single 100mA load (per transistor). Passerby Apr 17 `13 at 7:52
