I am relatively new to Arduino, but I want to improve the resolution on the analog pins on my Arduino Uno. As I am connecting a device that has a resolution of 12 bits, I want to be able to fully utilize this resolution. As the Uno provides only 10 bit resolution, I was wondering if anyone could refer some type of extra device that I can connect to my Uno in order to reach the desired resolution of 12 bits.
I see online that the Zero supports 12 bits, but Im not sure if I want order a new Arduino for this.
Any help will be immensely appreciated.
