hi, i made this bi led circuit below so that an arduino with 2 pins can change a single led
from red to green and off.
allthough it works great. I think my resistor values are a too low and may harm the transistors over time, yet when i raise the values the bi-led becomes duller.
here below is the circuit runing from a 5v regulated circuit ,
led spec:
Maximum Forward Current 25/30mA
Maximum Forward Voltage per Colour 2.5V
i wonder do these resistor values look o.k?
one objective was to make a small footprint.
Thanks for your help : )
