Hello,
Just curious to know how does normal analog potentiometers compare with i2c controlled digital potentiometers like DS1807 and compare with LED-LDR setup for volume control ?
For LED-LDR setup do we need to use optocoupler or can we use normal led and ldr and tape them together as shown in few threads here?
thanks and regards
