Uses a cheap 12V peristaltic pump and an ES8266 to dose chemicals into an aquarium using Micro Python.
I also decided to add a temperature probe to the aquarium just to track temps. I will probably send this to a MQTT server and use Home Assistant to graph/track the information.
- D1 -> OLED scl
- D2 -> OLED sda
- D4 -> DS18b20 data
- D5 -> IRF520 sig - pump
- D6 -> IRF520 sig - mixer
NOTE: need a 47nF capacitor across the output of the DC Motor Driver NOTE: need a 1N5817 diode across the output of the DC Motor Driver
