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)
** Arduino sketch **
[Available on my Github](https://github.com/fguiet/AutomationServer/tree/master/sketches/fishfeeder)
**Final note**
It's clearly obvious that you'll have to create your own fish tank hook...An upgrade of this project may be to provide an universal/versatile hook...
Have fun
