There are many software systems contributing to FarmBot's functionality. The diagram below shows the different components and how data flows between them. Read the brief descriptions of each component in the following sections to understand the system as a whole, and then dive into setting up the needed components for your FarmBot.

The web app allows you to easily configure and control your FarmBot from a web browser on your laptop, tablet, or smartphone. The application features real-time manual controls and logging, a sequence builder for creating custom routines for FarmBot to execute, and a drag-and-drop farm designer so you can graphically design and manage your farm.
The MQTT Gateway is a cloud application that acts as an intermediary for all messages between the FarmBot web app and FarmBot devices. It handles socket connections, device identification, and authentication.
FarmBot's Raspberry Pi uses this software to maintain a connection and synchronize with the web application via FarmBot Mesh. This allows FarmBot to download and execute scheduled events, be controlled in real-time, and upload logs and sensor data. The controller communicates with the Arduino over USB to send G and F code commands and also receive collected data.
This software is flashed onto FarmBot's Arduino MEGA 2560 microcontroller and is responsible for physically operating FarmBot's hardware, tools, sensors, and other electronics. It receives G and F codes from FarmBot Raspberry Pi Controller via the USB serial connection, and then moves the motors and reads and writes pins accordingly. It also sends collected data from the rotary encoders and pin reads back to the Raspberry Pi.
FarmBot OS has a WiFi Configurator utility built in allowing you to easily enter WiFi and web app credentials from a WiFi enabled device (such as a laptop or smartphone). This is useful for initial setup in order to get your FarmBot connected to your home WiFi.
OpenFarm is a free and open database for farming and gardening knowledge. This service provides crop and growing information to the web app for a streamlined user experienced.
OpenFarm is built by us too!
OpenFarm.cc was originally conceived as a small component of the FarmBot project. As progress was made, it became clear that OpenFarm had no reason to be tied to FarmBot, but could rather live on its own. In September of 2014, 1,605 people backed OpenFarm on Kickstarter. Today, OpenFarm is a standalone application, non-profit, and community. You can get involved with OpenFarm by joining the Slack channel, contributing on GitHub, or going to OpenFarm.cc and creating content!
