Hi guys,
i asked myself if it is possible to control 10 LEDs seperately by 10 distance sensors with an arduino uno? Are there enough I/Os or do i need something in addition?
I want the single LED to be switched off when the distance is smaller than eg. 5cm.
Thank you 
Daniel
Yes you can do this but you will need a port expander or shift registers to get the extra pins that you need.
What sensor? if it's analog output Mega or Due can handle that many analog signals.
If they are I2C, do they have different addresses? if yes, then no problem.
If they are on SPI, then you just need that many digital outputs to use as Chip Selects. Again the larger Arduino's have enough IO.

Yes but the OP already stated that he has a Uno.
