Can the MCP23017 expand Analog In pins?

Post by TeamObstant »

I'm interested in increasing the number of analog in pins on my Arduiono Uno. Would the general purpose ports added by the MCP23017 - i2c 16 be able to use the analogRead() function?

No. That is a digital only device. To extend your analog capabilities, you can use:
MCP3008: https://www.adafruit.com/product/856
ADS1015: https://www.adafruit.com/product/1083
ADS1115: https://www.adafruit.com/products/1085
