arduino - How is binary converted to electrical signals?


I'm just starting off in electronics and am already fascinated. Having played with an Arduino these past few days I'm aware that binary is a representation of different voltages - such as +5V representing 1 and GND representing 0.



I've been trying to discover how, at a physical level, the microcontroller converts the binary to these voltages. I cant seem to find a description anywhere. Can anyone share their knowledge or point me to a place/good book that describes how this works?

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...
