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
• 28BYJ-48 step motor + ULN2003 module (easily found on Aliexpress)
• USB charger
• Brass insert/Insert nuts

Arduino sketch

Available on my Github

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
