Ok so what you will need to setup the PicoFarmLED-OS is any esp-32 based prototyping board.

Make sure it's an esp32-wroom32 with at least 4MB or flash.

The setup is quite simple, this guide will take you through the setup using either windows, or any Unix OS (linux/macOSX)

Click the link below to download the firmware files for the PicoFarmLED-OS.

If you'd rather compile from source, the github repository link is below too.

Once downloaded unzip the archive, and continue to the next section for windows, or skip to the right section for your OS.

For windows the best is to use the flash download tools below.

Once downloaded run the executable, select ESP-32 as chip type and Develop as work mode.

Uncheck the LockSettings checkbox to unlock the interface.

At the top of the application you will find an empty list of paths, fill them like the screenshot on the left.
Each box has to be filled with the corresponding file and address as listed:

• ota_data_initial.bin at 0xd000
• bootloader.bin at 0x1000
• firmware.bin at 0x10000
• partitions.bin at 0x8000
• spiffs.bin at 0x3f0000

Make sure each file's checkbox on the left is checked.

At the bottom of the application you can find the flashing section.

First connect your esp-32 board to your computer using the usb cable.

Select the COM for your board, if you are not sure which one, disconnect your board to see which one disappears.

BAUD should be at 921600.

Click the START button to start flashing your device.

The archive comes with two bash scripts that will flash the firmware.

They work with python, so make sure you have it installed.

Open a terminal.

First step is to locate you serial port device file. To do so, unplug your esp-32, then type `ls /dev/tty*`, it will output a list of files. Plug your esp-32 in your computer and restart the previous command.
Note that there is at list one new file, this is your esp-32.

Let's set it as an environment variable with the command:

export SERIAL_PORT=/dev/ttyUSB0

(replace ttyUSB0 with the device file you found above)

Use the `cd [ insert files path location ]` command to navigate your terminal to the location of the downloaded files.

You're now ready to flash your esp-32, run this command:

./flash.sh && ./write_spiffs.sh

Ok now your esp-32 is ready to run PicoFarmLED!

To make sure it's running, look at your wifi list, you should see a new wifi called 🤖🍁
Connect to it with the `multipass` password, and navigate to http://192.168.4.1/fs/app.html to display the control interface.

Here is the final schematic we want to have at the end.

If you're not sure how to do it, just follow the guide:)

First thing to do is insert the white wire included in the kit.

FYI: It's a JST-XH 3-pins.

Here's the pinout on the other end of the white wire once plugged in.

Ok let's first setup the 24v wire.

Take the first wago plug and insert the V+ wire coming from the power supply.

Checkout the guides below to see how to prepare your power supply.

Now take the second wago plug and insert the ground wire from the power supply.

Ok, now we have our power wagos setup.

Let's plug the 24v power to the LED panel.

Make sure to use the right pin in the white wire!

24v is the middle pin.

Now take the Ground wago.

Add a jumper wire between the arduino GND gpio and the V- pin of the white wire.

Alright, now we need to link the GND from the system to the controller.
Add a jumper wire to the Wago #2, and plug that jumper to a GND gpio of your arduino.

And now we're going to plug the controlling jumper.
Add a jumper wire to the pin IO33, then plug that jumper wire to the white wire hole named "PWM".

The firmware is compatible with the following sensors:

• SHT2x: temperature and humidity
• SCD30: temperature, humidity and CO2
• HX711: weight sensor, experimental, the idea is to detect when the soil needs watering

Those sensors are using the i2c protocol, which means they have 4 wires:

• GND: goes to a GND pin of the esp-32
• 3v: goes to the 3.3v pin of the esp-32
• SDA: goes to the gpio 18 of the esp-32
• SCL: goes to the gpio 5 of the esp-32

Aaand there's a little bonus.
You can either use your newly setup controller through its admin web interface.

Or you can use the SuperGreenLab app on your appstore!
