uses a micro USB cable to connect to the Arduino and select the "Arduino Mega or Mega 2560" board in the IDE ("Tools" -> "Board").

Assembly

Water level sensors

The water levels sensors are used for:

protects the sump pump (preventing it from running without water)
automation of water replenishment due evaporation losses
automation of the partial water change (PWC) routine

The water levels sensors are optional, in the sense that their use can be disabled using the configuration flags. However, the features above will be suppressed. As shown in the figure bellow, the sensors are expected to be mounted as closed for full water level and opened for low water level.

Pumps and sensors schema

The figure bellow, shows the main solution components with focus on water pumps and water level sensors:

"drain" pump and "drain" water level sensor are mounted at aquarium/fisk tank as show (with the "drain" water level sensors at maximum aquarium level)
"sump" pump and "sump" water level sensor are mounted at sump tank as show (with the "sump" water level sensors at minimum level for sump pump safety)
"water reposition" pump is mounted a external water container ("water reposition tank)

The "drain" water level sensor and "water reposition" pump work together in the automation of water replenishment due evaporation losses (optional, see config flags). Whenever the water level drops (at water level sensor), the water reposition pump pushes more water into the fisk tank (keeping it stable). This feature is optional and can be disabled using the configuration flags. In that case, "water reposition container", "water reposition pump" and the water level sensor can be dismissed. Notice that the flow performance demand over the "water reposition pump" is very low, and a really cheap / low flow pump (~ 3w) is strongly recommended.

As expected, the "sump" pump pushed water from sump back into fisk tank. The "sump" water sensor level turn of the sump pump case water level is to low (preventing it from running without water).

More over, "sump" pump, "sumo" water level sensor, "drain" pump and "drain" water level sensor work together in the automation of the partial water change (PWC) routine (optional, see config flags). Using a ingenious teamwork, the solution perform 2 main steps:

step 1: removes dirt water from aquarium / fisk tank into waste/sink
step 2: pushes water from the external water container (with conditioned water) into aquarium / fisk tank, until the original water level.

This feature is also optional and can be disabled using the configuration flags. In that case, "water reposition container", "water reposition pump", "drain" pump and "drain" water level sensor can be dismissed. Notice that the flow performance demand over the "drain pump" is also very low (a slower PWC is better for the fishes), and a really cheap / low flow pump (~ 3w) is also strongly recommended.

Furthermore, the code was designed to use a minimum amount of water level sensors. However, you can improve the setup adding independent water level sensors for maximum aquarium level and PWC stop level. You can also include a water level sensor at external water container ("water reposition tank") in order to alarm and/or protect the "water reposition" pump.

Feeder

Using feeder feature (ENABLE_FEEDING true) requires an fish food container that can dispense it to the fisk tank. There are two possible options:

integrates an external feeder (e.g., Boyu feeder) (FEEDING_AS_PUSH_BUTTON true)
making a feeder from scratch using a stepper motor (FEEDING_AS_PUSH_BUTTON false)

Integrating external feeder

This configuration (FEEDING_AS_PUSH_BUTTON true) assumes to control an external feeder (e.g., Boyu - that I already have!), and requires disassembly it and a little wiring. Connects (parallel) the "feed" push button of your feeder (both terminals) to the "normally open" pins of your relay pins (RELAY_FEEDER_PIN). Therefore, the relay can simulate a user button press (and the feeder push button still working independently, just as before...).

Stepper motor feeder

This configuration (FEEDING_AS_PUSH_BUTTON false) assumes making a feeder from scratch using a stepper motor (and driver).
On that step, the stepper motor will the specified number of turns in order to feed the fishes. The simpler way of do the "mechanical" parts of the feeder is to fix and small plastic bottle on stepper motor axis. Make one hole (transversal) in the bottle in order to pass the food as the bottle rotates,
like this or this. Alternatively, you can use any kind of drill or even wire do drive the food. In this step up, the relay pin (RELAY_FEEDER_PIN) is free to be used as an extra relay for any application (the same if feeding routine is disabled at all - ENABLE_FEEDING false).

Furthermore

Default timers (basic timers - without home assistant integration)

Timers and alarms can be programmed (number entities and/or home assistant command topic) and stored at EEPROM, however, default values will be saved otherwise (change that if required for standalone use):

macro	value (default)	description
DEFAULT_ALARM_BOUND_TEMP_MAX	26.0	minimum water temperature in Celsius (alarm/heater)
DEFAULT_ALARM_BOUND_TEMP_MIN	29.1	maximum water temperature in Celsius (alarm/cooler)
DEFAULT_ALARM_BOUND_PH_MAX	8.9	maximum Ph (alarm)
DEFAULT_ALARM_BOUND_PH_MIN	7.5	minimum Ph (alarm)
DEFAULT_TIMER_LIGHT_ON	6	light turn on time (hour of the day)
DEFAULT_TIMER_LIGHT_OFF	23	light turn off time (hour of the day)
DEFAULT_TIMER_UV_ON	8	UV filter turn on time (hour of the day)
DEFAULT_TIMER_UV_OFF	15	UV filter turn off time (hour of the day)
DEFAULT_TIMER_FEED_1	7	1st Feeding time (hour of the day)
DEFAULT_TIMER_FEED_2	12	2nd Feeding time (hour of the day)
DEFAULT_TIMER_FEED_3	18	3th Feeding time (hour of the day)
