DS3231-based alarm clock
I 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 MoreTo save valuable flash memory on ATtinys when using I2C, you can use alternatives to Wire.h such as TinyWireM. I show how it works.
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 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 MoreIn 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.
Read MoreI present the ICM-20948 9-axis sensor and my associated library. The ICM-20948 is the successor to the MPU-9250. This is Part 1.
Read MoreI introduce the ESP32 and its main features. In particular, I will discuss the differences to the Arduino (AVR) boards.
Read MoreI will show you how to use the two I2C interfaces of the ESP32 and which requirements libraries of I2C components must have for this.
Read MoreI show you how to use up to eight I2C components with the same address with the I2C multiplexer TCA9548A. Alternatively, you can use MOSFETs as well for this purpose.
Read MoreThe ADXL345 is a 3-axis accelerometer with many features. I explain how to use it with my associated library.
