The Arduino UNO Q redefines embedded development! This Hybrid SBC pairs a 2.0GHz Qualcomm MPU (running Debian Linux) with a real-time STM32 MCU. Use it headless via SSH, as a standalone PC with 1080p output, or with the App Lab workflow. Compare it with the ESP32-S31, discover the high-res pinout, the A0-A5 5V trap, and master all 4 development workflows!
The MPU-6500 is a compact, low-power 6-axis MEMS MotionTracking sensor combining a 3-axis gyroscope and a 3-axis accelerometer on a single chip. Communicating via I2C (up to 400 kHz) or SPI (up to 20 MHz), it features an onboard Digital Motion Processor (DMP) to offload complex motion fusion algorithms, ideal for drones, IoT, and wearables.
Forget servers, brokers and Wi-Fi. The IPS reverse architecture turns UWB tracking inside out: passive tags on the walls act as lighthouses, while your robot carries the brains and computes its own position on board, exactly like a personal GPS. Full guide with Arduino, ESP32 and the RYUW122 module.
I have news for those who have been following mischianti.org for a while: I’m officially launching an initiative I’ve had in mind for a long time. Every year I draw up to 5 software bundles (JetBrains All Products Pack + AiNonymizer) among the most active contributors to the site and the forum.
I’d like to renew my cnc for PCB so I decide to create new one from an existing project named Cyclone PCB Factory.
Introduction and mechanical part.

The PCF8574 I/O expander adds 8 digital pins using only the two-wire I2C bus (SDA and SCL), letting you drive up to 4 HC-SR04 ultrasonic sensors from a single chip. This guide covers the wiring diagrams for ESP32 and Arduino UNO, the I2C addresses, complete code with ping_cm_poll(), median filtering for stable readings, the pulseIn/pulseInPoll primitives and how to pick the right polling interval without saturating the bus.
In this guide, we dive deep into the Standard Trilateration Architecture using the Reyax RYUW122 module. We will explore why “centralized intelligence” is the secret weapon for optimizing coverage and how this setup differs from other positioning strategies.
Discover how to use the HC-SR04 ultrasonic sensor with Arduino, ESP32, and ESP8266. Learn its time-of-flight principle, safe wiring and voltage-level considerations, practical code with pulseIn() and NewPing, plus advanced multi-sensor modes for reliable distance measurement.
The HC-SR04 is an ultrasonic sensor that measures distances from 2cm to 400cm using the Time-of-Flight (ToF) principle. It emits a 40 kHz sound pulse and calculates the echo’s return time. It provides reliable detection regardless of ambient light, identifying transparent and liquid surfaces.
Monitoring soil temperature and moisture with industrial-grade reliability has never been easier. In this guide, we’ll walk you through using the ZTS-3000-WS-N01 RS485 soil sensor with the ZTS3000_RS485 Arduino library. You’ll learn how to wire your hardware, install the library, perform basic soil measurements, and apply advanced calibration commands, all using familiar Arduino sketches.
Turn your ESP32 into a high-performance multi-session FTP server with the MultiFTPServer library. A complete guide covering FtpServerKey.h configuration, a comparison of SPIFFS, LittleFS, FFat and SD card filesystems, real-time monitoring callbacks, FileZilla optimization for multiple connections, and ready-to-use code examples.
