Read MoreI show how to use a MOSFET as a switch and which parameters are relevant for the selection of the right MOSFET.
Read MoreCompared to I2C-based EEPROMs, writing data to SPI EEPROMs is faster, especially for bulk uploads. I explain how this works and will introduce my library for the SPI based EEPROMs.
Read MoreI show how you can use I2C controlled EEPROM ICs with your microcontroller. This works very comfortably with a library, but it can also be done without it.
Read MoreAVR microcontrollers have an EEPROM in which you can store data permanently. I show you how to write to and read from it.
Read MoreThe 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.
Read MoreBlynk is an easy-to-use IoT platform that allows you to control microcontrollers remotely. This is an introduction.
Read MoreI will show you how to build a WiFi BBQ thermometer with a temperature sensor, an ESP32 board and a few other components.
Read MoreI will show you how to build a wireless 433 MHz BBQ thermometer with alert function and graphical display of the temperature curve.
Read MoreI show you step by step how to network and control your ESP32 or ESP8266 boards via WLAN and how to exchange data between them.
