Yet Another Hydroponics Project (YAHP)

Yet Another Hydroponics Project (YAHP)

I am quite often thoughtless when it comes to taking care of plants. This is why I started to create something using Arduino. Yet Another Hydroponics Project (YAHP) is an attempt at remote controlling the status of a small greenhouse, and at providing automatic irrigation and lighting.

Step 1: Installation

The development kit used for this project is a ESP32 Dev Module, and the documentation refers to that module. However, any ESP32 board should do the trick.

In order to replicate the project, you will need to follow the circuit (sorry, no schematics for the moment) and install the files.

This is an IoT project: you need to provide the secrets for the connection!

Step 2: Assemble the circuit

The circuit can be assembled as in the figure:

N.B.: in the v2, the hardware button has been removed completely from the sketch (IoT buttons are used).
