An Aquaponics system using Raspberry Pi brain and an Arduino controller

#Setting up as a service Compile the plantduino executible, this is what the service will try to run. go build plantduino.go

Copy plantduino.service to /lib/systemd/system/ cp plantduino.service /lib/systemd/system/

Reload daemon and add the new service sudo systemctl daemon-reload sudo systemctl enable plantduino.service

Now either restart the system: sudo reboot Or just start the service: sudo systemctl start plantduino.service

#Compiling and uploading to arduino from the Raspberry Pi I used the Arduino CLI so I did not have to have a UI.

Install the CLI by running: curl -fsSL https://raw.githubusercontent.com/arduino/arduino-cli/master/install.sh | BINDIR=~/usr/bin sh Full official instructions here: https://arduino.github.io/arduino-cli/installation/

Check it is installed correctly by just calling: arduino-cli This should give you the help message

Create a config file: arduino-cli config init

Move to the Plantduino Arduino code directory: cd Arduino The Arduino CLI requires you to be at the top level of project, do not go into the "plantduino" dorectory where the code actually is of the compile and upload commands will not work.

Get the CLI index arduino-cli core update-index

Check if your Arduino is found arduino-cli board list If your arduino is a cheap rip off one like mine it will not be identified in the FQBN section, this is fine we can specify it.

Download the core for our board arduino-cli board listall arduino:avr (This was fairly slow of my RPi, it looked like it had crashed but eventually just finished)

Compile the sketch arduino-cli compile --fqbn arduino:avr:nano plantduino

Upload to the Arduino arduino-cli upload -p /dev/ttyUSB0 --fqbn arduino:avr:nano plantduino Replace ttyUSB0 with the ID you got from the arduino-cli board list command
