Fish feeder

Hi,

Sick and tired of feeding the fish :)
Here is the answer : The Ultimate Fish Feeder.

Get ready for 16 days of freedom :)

**How it works**

This project is using MQTT and Node-Red. Basically, nothing complex in here: The Ultimate Fish Feeder is subscribing to a MQTT topic. Each day, a Node-Red flow is emitting that topic and that will do the trick : fed is the fish :)

**Sofware needed**

* Node-Red
* MQTT

**Electronic spare parts required**

* [Wemos D1 mini](https://wiki.wemos.cc/products:d1:d1_mini)
* 28BYJ-48 step motor + ULN2003 module (easily found on Aliexpress)
* USB charger
* [Brass insert/Insert nuts](https://www.aliexpress.com/wholesale?catId=0&initiative_id=AS_20190915022727&SearchText=insert+nut&switch_new_app=y)

**Final note**
It's clearly obvious that you'll have to create your own fish tank hook...An upgrade of
