If you want to get started with motion sensors and the like, ESPHome makes it incredibly easy to build your own sensors.

It’s all the stuff you’d find incorporated on a little dev board, without the ESP32, so while it’s nothing earth-shattering it’s also a neat and useful little addition to your arsenal.

You'll also find a course that teaches you how to program ESP32 without traditional coding. By the end of these courses, total beginners will know how to use microcontrollers with confidence.

If you want to try a Scratch-inspired take on microcontroller programming, check out MicroBlocks. It will work with several common boards, including the micro:bit and the Raspberry Pi Pico.

Since it’s a YAML file, you’ll want to set up the correct indentation for it. Be sure to update the Wi-Fi credentials inside the configuration file before flashing the new code to the ESP32.

Designed by Namnam in Vietnam, the ESP32 Modbus gateway is built to communicate with PLCs and industrial sensors over Modbus ...

After an introduction that includes a crash course in C programming basics, users get training in how to connect Arduino boards with ESP32 for full web connectivity.
