Fish feeder

thingiverse

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
