Is it possible to have two rotary potentiometers read from a single analog input pin?
The analog input is 10 bits (0-1023), so each pot would have 5 bit precision (0-15).
Least significant bits for pot 1 and most significant bits for pot 2.
A SPI/I2C ADC IC (eg. MCP3008) is an option if this is not possible.
The two pots do not need to be read at the same time. It seems full 10 bit precision could be achieved if I use a digital pin to enable each pot before it is read.
