Using 10 photo resistors


I wanted to use 10 photo resistors on one Arduino board, is there a way to multiplex an analog port, or could I use i2c sensors daisy chained?

Thanks, Nat

Yes to both. 8:1 analog muxes are readily available. I2C sensors, not sure what you have in mind. I2C ADC chips with multiple inputs are available, can provide higher resolution and faster conversion speed than the 328P's 10 bit, 100uS/conversion ADC.
