IOT plant watering system, so my plants don't die when I'm on vacation ;)

Flora IOT

This is a personal project used to water my plants when I'm not home :)

Hardware:

----------
| pico_w |- VBUS/GND -- 12V power adapter with a step down converter to 5V
|        |- GPIO26 -- moisture sensor's analog output
|        |- GPIO2  -- DC-DC relay that powers on a small water valve
|--------|

for more look in: source/gpio_conf.h

Building and running:

1. cmake -B build -DWIFI_PWD='your WiFi password' -DWIFI_SSID='your WiFi's SSID' -G Ninja -DPICO_SDK_PATH=path/to/pico-sdk
2. ninja -C build
3. Plug in the pico with a usb cable with bootsel button pressed, then use whatever you like (dd/file manager etc) to move the binary (build/flora.uf2) to pico's flash.
4. Use a serial terminal app of choice (picocom/minicom etc) and open up the device (e.g. /dev/ttyACM0) to get the device's assigned IP and see the log output.
