Welcome to the MicroPython Course!

This course is designed to provide you with a comprehensive introduction to building an IoT project with MicroPython on the ESP32. You will learn how to read sensor data, control a water pump, communicate via MQTT, and create a dashboard for remote monitoring - all through hands-on code examples!

Course overview

Setup & Basics: Introduction to MicroPython, flashing the ESP32 with the firmware, setting up your development environment and learn the basics of MicroPython by controlling the onboard LED.
Sensor Integration: Interface with a soil moisture sensor to monitor your plant’s water needs.
Actuator Control: Learn to drive a pump (via a relay module) based on sensor readings.
MQTT Communication: Transmit sensor data and receive remote commands using MQTT.
Dashboard Development: Create an interactive dashboard to visualize sensor data and control your watering system.

In this course, we use MicroPython running on the ESP32 along with these great tools:

Sneak peek

Here is a sneak peek of selected topics we cover in this course:

MicroPython Basics & LED Control

Learn how to flash your ESP32 with MicroPython and start by blinking the onboard LED.
Sensor Integration

Read data from a soil moisture sensor to detect your plant’s water needs.
Pump Control

Control a water pump (via a relay) to automate the irrigation process.
MQTT Communication

Transmit sensor data and receive remote commands using MQTT for real-time control.
Dashboard Development

Build a user-friendly dashboard to monitor sensor readings and control the pump.
