EEPROM Part 1 – AVR internal EEPROMs

AVR microcontrollers have an EEPROM in which you can store data permanently. I show you how to write to and read from it.

Logic Analyzer

The Logic Analyzer is a low-cost tool that allows you to analyze signals such as I2C, SPI, PWM and much more. I introduce the Analyzer and the Logic 2 software.

Blynk – An Introduction

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

WiFi BBQ thermometer

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

Wireless BBQ thermometer (433 MHz)

I will show you how to build a wireless 433 MHz BBQ thermometer with alert function and graphical display of the temperature curve.

Using WiFi with the ESP8266 and ESP32

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.

SIM800L module

With the SIM800L, you can add mobile phone functions to your projects, e.g. make calls or send measured values via SMS and much more.

Strain gauges

With strain gauges you can measure the strain and bending of components. I’ll show you how to use them with the HX711 or op amps.

Programming the ESP32 with MicroPython

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.

MicroPython – Switching from Arduino

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