MPU9250 – 9-Axis Sensor Module – Part 1

The MPU9250 is an accelerometer, gyroscope, magnetometer and thermometer. I present its technical characteristics and give an introduction to my library.

HC-12 Radio Module

The HC-12 radio module is easy to handle and has a long range. I’ll show you how it works, how you make settings, and how you use it legally compliant (in Germany).

DCF77 – Radio Controlled Clock

Here you will learn what the DCF77 radio clock signal is, how to receive it, how to evaluate it and how to use it optimally together with the library RTCLib.

DS3231 – Real-time clock

In this article I will present the features of the real-time clock (RTC) DS3231 and how you can use it with the RTCLib library.

ADXL345 – The Universal Accelerometer – Part 2

In the second part of my article about the ADXL345 and my library I go into Activity/Inactivity, Single and Double Taps and FIFO.

ADXL345 – The Universal Accelerometer – Part 1

The ADXL345 is a 3-axis accelerometer with many features. I explain how to use it with my associated library.

MMA7361 – Analog Accelerometer

I show you how to use the analog 3-axis accelerometer MMA7361 to determine acceleration, angle and orientation and how to use the free fall interrupt.
