Controlling Raspberry Pi over REST input

Initial Position We would like to control a wind machine over the internet in realtime. The wind machine is there for a simulation of different wind speeds. The idea is that a presenter has an iPad with which he can either choose a preprogrammed show or has a slider where he can control the speed manually. We have a raspberry pi where a shield is connected. Currently we output it to a lamp since it uses the same PWM technology. (see attachment) You would need to write a program for the raspberry pi which would take an input from our Realtime Firebase DB (REST) and output it to the wind machine. Possible Solution (see Video at 14min) [login to view URL] [login to view URL] Requirements - low latency between input and output (<1 sec. the internet connection will be fast enough) - easing (ramp up, ramp down) between the different outputs - final program should boot up at start, so that the presenter can only start the raspberry pi and the system will be ready to use. - in your response, please include "hello crunch" and if you already did some similar projects Deadline 20.
