SCD4x CO₂ sensors
I introduce the SCD4x CO₂ sensor modules and show you how to control them using the Sensirion library. I also check their reliability in comparison with a commercial measuring device.

Read MoreI present concepts for a DS3231-based alarm clock. The alarm clock is controlled with only two buttons and a slide switch. I use the Nokia 5110 and the DOGS164 as energy-saving displays.
Read MoreThe microcontrollers of the tinyAVR family differ significantly from the classic ATtinys. This is an introduction to programming at register level.
Read MoreWith the HC-14 module, you can use LoRa wireless technology very conveniently via simple serial functions such as println(). I’ll show you how it works.
Read MoreIn this article, you will learn how Serial and SoftwareSerial work, which functions are available to you and how to use them.
Read MoreWith the Ebyte LoRa modules from the E220, E20 and E32 series, you can send data over long distances with low energy consumption. An overview and introduction.
Read MoreCharacter arrays are less convenient than strings, but save resources. I show that character arrays are in no way inferior to strings in terms of functionality.
Read MoreFreeRTOS is a real-time system, with which multitasking can also be realized on relatively small MCUs. This article is an introduction to the topic, whereby I will limit myself to the ESP32 and the AVR-based Arduinos.
Read MoreThe Arduino Nano Every is much more than just an upgraded Arduino Nano. Its underlying ATmega4809 opens up a wide range of possibilities. The article provides an in-depth insight.
