Analog Modem Design Project Using Atmega

Leave a Comment / Using Atmega / By Tech Master

Introduction: We thought it would be interesting to try and construct a simple modem out of the ATMEL 8535. The main motivation for doing this was to test some DSP theories about the effects of transmission power, noise, and modulation technique on the bit error rate. Initially, we wanted to connect our modem to the …

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 …
