Why can computer circuits recognise only two states?


Computers can only understand binary (that is 0s or 1s). I want to know Is there any way that computers can understand more than 2 states. I know that It is much harder to build components that use more than two states/levels/whatever. Of course If we have more than two states we would be able to hold more data per bit, just like our decimal number system can hold far more data in a single digit.

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
