Extend analog inputs/outputs

Using Arduino Microcontrollers
#1

Regars,

i´m develping an project tha involves more than 16 analog sensors, i´m considering use an arduino mega, but i was wondering if there is any other model that can allow more than 16 analog inputs.

i´m cosidering too use an multiplexer but im trying to reduce costs

regards

You can use an analog multiplexer/demultiplexer (as the Arduino uses internally too) to connect up to 8 different analog sensors to each analog input of the Arduino. Using an UNO you get up to 48 analog input channels.

One example you could find in the playground.
