1) Objective:
IntoRobot Nut is a tiny  open-source Wi-Fi MCU board to develop IoT projects. It is easy to use, powerful and cost-effective. If you are new to Nut MCU, please read the NUT Quick Start in http://osoyoo.com/2016/11/15/intorobot-nut-quickstart/
IntoRobot NUT has an integrated Light sensor which can get light strength value of the environtment. In this project, we will use IntoRobot to get environment light data and send it to IntoRobot IOT cloud, then we will use browser and mobile app to read the real-time data from internet.
