Zapro:
Look at this pic. You can place the LED in two ways. One way, it lights up when the output of the Arduino is "High" and the other, it will light when it is "Low"// Per.
I want to trigger LED when voltage is HIGH and this is exactly what I already tried, but connecting LED with series resistor like this reduces input voltage to driver input pin from 5V to 3V because of the series resistor, so I feel that this is not the best way to approach.
Or you trying to say that it doesn't matter that I have voltage drop? Sorry I still confused about this...
