How removing CMOS battery can bring PC back to life This weekend, I faced every tech enthusiast’s nightmare. Over the weekend, I updated my home server, made all regular backups, copied them to an...

This cheat sheet provides a quick reference guide for working with Podman, a container runtime similar to Docker.

Intro What are suitable batteries for powering Arduino or microcontrollers in general? Hopefully, Arduino (or rather ATmega328P controller) can be powered by basically anything between 1.8 and ...

Motivation I decided to explore power consumption of Arduino Pro Mini and use sleep mode to get power consumption as low as possible so data logger can be powered from battery. I had some notes fr...

Introduction In this article, we’ll explore how (not) to build a simple data logger using an Arduino board, a BME280 sensor, a DS3231 Real-Time Clock (RTC) module, and an external EEPROM chip. T...

This comprehensive guide demonstrates using an external EEPROM chip with Arduino for data storage. It covers I2C communication, Arduino's byte order, and code examples for writing/reading data, including simulated measurements. Crucially, it addresses the issue of writing across EEPROM page boundaries which corrupts data. The article explains the problem, provides relevant datasheets, code examples to illustrate it, and offers a solution for handling page boundary writes correctly to ensure data integrity. A valuable resource for working with external EEPROM and MCUs.

Comprehensive guide on using the DS3231M real-time clock module with Arduino. Learn to read and set the current time, wake up Arduino from sleep mode using RTC interrupts, and integrate precise timekeeping in your projects. Includes well-explained code examples and troubleshooting tips.

Learn how to connect and use the Nokia 5110 LCD display with a Raspberry Pi Pico using MicroPython. Tutorial covers the wiring, code implementation, and troubleshooting tips.

Explore the basics of Raspberry Pi Pico and MicroPython. Learn how to set up your board, install MicroPython, and start programming with a simple LED example.

A guide on using environmental sensors like HTU21D, BMP280, BMP388, and DS18B20 with Arduino boards for monitoring temperature, humidity, and pressure. Includes wiring instructions, code examples, and project ideas for weather stations and data logging.

Introduction Target Audience Arduino articles are meant to be somewhat concise, if steps are easy. There are plenty of really in-depth resources for beginners. On the other hand, unlike other ard...

An in-depth exploration of finding the center of rotation from 2x3 and 3x3 transformation matrices, with analytical solutions, Python code using SymPy, and an alternative approach involving eigenvectors. Covers the challenges faced, mathematical derivations, and practical applications in computer vision and image processing.

Introduction Starting with simple examples and moving towards more complex ones is a widely accepted teaching method. However, I consider this approach to be somewhat redundant for our purposes, a...
