Blynk is an easy-to-use IoT platform that allows you to control microcontrollers remotely. This is an introduction.

I will show you how to build a WiFi BBQ thermometer with a temperature sensor, an ESP32 board and a few other components.

I show you step by step how to network and control your ESP32 or ESP8266 boards via WLAN and how to exchange data between them.

In this post, I show you how to program the ESP32 with MicroPython. I go into detail about the A/D converters, I2C, timers, RTC, touch pins, etc.

This is a MicroPython crash course for people with Arduino/C++ experience. I use the ESP32 as the MCU and uPyCraft as the IDE.

I introduce the ESP32 and its main features. In particular, I will discuss the differences to the Arduino (AVR) boards.

I will show you how to use the two I2C interfaces of the ESP32 and which requirements libraries of I2C components must have for this.

Hall sensors and reed switches are electrical components that respond to magnetic fields. I show which variants there are and how to use them.
