Usando uma câmera Intel RealSense 3D com uma placa Intel Edison

Neste artigo, veremos como compartilhar a placa Intel Edison com a câmera RealSense 3D. Criaremos dois aplicativos, um deles usa uma câmera 3D Intel RealSense para análise de gestos e uma placa Intel Edison para alternar os LEDs na placa. O segundo aplicativo usa a placa Intel Edison para receber dados de sensores de temperatura e o Intel RealSense para sintetizar voz para ler informações de temperatura.
