Controle de Iluminação Residencial por Comandos de Voz

Componentes e Materiais

• 1x Arduino UNO
• 1x 1Sheeld
• 3x LEDs (cores diferentes: azul, amarelo, verde)

Sobre o Projeto

A ideia era provar que é possível controlar a iluminação da casa usando apenas comandos de voz. Os 3 LEDs representam diferentes sistemas da casa (exemplo).

Materiais Necessários

1. Arduino Uno
2. 1Sheeld
3. 3 LEDs (cores diferentes)

Monte o circuito conforme o esquema abaixo:

Configuração do 1Sheeld

1. Abra o app 1Sheeld e conecte ao seu hardware 1Sheeld.
2. Selecione o shield Voice Recognition (Reconhecimento de Voz).
