    Wanted the fan to stop when the light in the bathroom is ON, but i found it a bit redundant since I could pre-set fan speeds for various humidity levels and even stop it if the humidity reaches an acceptable low level.

    Hi Mike,
    Thanks for your comment/question.
    I also thought about putting everything on one board & my first attempt was with a Wemos D1 R2 board but it somehow didn't work. I'm not very sure which part of the coding I was missing (as coding is not my strength & maybe the board I'm using is a cheap clone?).
    For the time being, I plan the esp8266 to only work as the link between the Amazon Echo and the Nano board. I believe if the code is too long in the esp8266, it'll slow down its response to voice-commands as well? Also, in the near future, I intend to expand the functions on the Nano board to include elements such as temp/humidity sensing to control my portable evaporative cooler, just in time for the dry summer heat in Australia.
    Well, if you have an improved approach, I'm sure a lot of people (including me) would be happy to expand on your idea.
    Cheers

    Please note that the actual (large) 7-segment display used in this project requires around 8V to work. The final wiring differs from the simulation digram on Tinkercad. The online simulation platform only provides small 7-segment displays which runs on lower voltages and can be connected directly to the digital outputs of the Arduino with the appropriate use of protective resistors.
