wondering if it is possible to and an led for on off maybe one for turbo on and off to..
I don't see an output for a turbo indicator LED on the Xin-Mo.
The good news is an on/off LED is very easy to add.
Pretty sure that Pin 2 on your Xin-Mo is VCC (operating voltage) -- it
should be 5v, but verify with your multimeter.
All you need to do is:
- Choose an LED with known voltage and current ratings
- Enter "Source voltage" (VCC), "diode forward voltage" (LED voltage rating), and "diode forward current" (LED current rating in mA) into the calculator
here to find the correct resistance and wattage specs for a current limiting resistor
- Hook it up
VCC ---- resistor ---- +LED- ---- GND
