Analog to Digital Converter of ATmega32 with LED Display

Leave a Comment / LED Projects / By Tech Master

Microcontrollers are capable of detecting binary signals: is the button pressed or not? These are digital signals. When a microcontroller is powered from five volt, it understands zero volts (0V) as a binary 0 and five volts (5V) as a binary 1. But the real world is not so simple and likes to use shades …
