Once I'm fairly certain the new design is feasible, it will be easier to work with a soldered board. Less wires to deal with.
This can be on a perfboard or breadboard, depending on how cramped the design will be.

By design, during runtime we don't allow loading a configuration, since there is too much room for bugs regarding resetting things to a valid state.
So, the easiest and safest way is to have a very simple menu at startup with:

• Two big buttons far apart (Load Config, Reset Config)
• Label explaining to pick an option
• Countdown (maybe ~3-5 seconds). If no option is picked, it defaults to Load. This is needed so that when there is a power cut, the system can resume.
• If "Reset Config" is pressed, disable the countdown and ask for confirmation. No need to for a button to go back. The user can just reset to go back.

The new version will use a different microcontroller and some different components in the board itself.
The entire previous code need to be ported to the point we have feature parity with the previous state.

• Refactor pin code to work with the new design
• Refactor logging code and console to work with the new design
• Refactor gfx code to work with the new design

The old version used some components that were not compatible with 3.3v logic/voltage, such as the L293D to control the motors.
A new design is needed that can be used with 3.3v, and potentially also usable with 5v with minor changes.

Things I can think of that should be done as part of this task:

• Design new version with Fritzing

Confirm the new design is probably ok by testing various things with temporary code

• I2C in general seems ok ?
• Display
• Touch
• Soil moisture sensor reading
• Temperature and humidity sensor reading

Ideally we should have a proper project enclosure to protect the components and makes things look neat and tidy
Googling for "diy project enclosure" shows up a couple of interesting things.

The Arduino Nano RP2040 Connect has Wifi, and it's probably the board I will end up targeting.

It would be nice to have some kind of online component where we can check for example:

• Check relevant logs
• Change settings
• Software reset (if that is possible?)
