/*
  Cadeira Inteligente
 Código para controle de Cadeira de Rodas.
 
 O Código lê o nível de sinal nas portas analógicas A0 e A1, 
 A0 indica se deve ir para frente ou para traz.
 A1 indica se deve dar mais potência para Direita ou para Esquerda
 
 Foram criadas algumas constantes, para facilitar o ajuste de valores para calibração do código.
