Description
Description
Aqui está uma visão pictórica de um sistema Arduino autônomo em uma placa de ensaio. Esta versão basicamente duplica o modelo serial do Arduino, com uma pequena alteração. Você pode ver no esquema que alguns componentes foram removidos e um novo foi adicionado. O inversor hexagonal 7404N substitui os conjuntos de transistores RX e TX na placa serial. É apenas uma maneira conveniente de inverter o sinal serial de um computador de programação para o ATMega8.
