This article explains what a load cell is and how it works. It shows how to use the HX711 amplifier to read weight values with a microcontroller, how to calibrate the system, and includes a practical MIDI controller project example based on load cell input.

This article explains what stepper motors are and how they work. It covers basic motor characteristics, shows how to control a stepper motor using an Arduino and a driver module, and presents a practical project where the motor is controlled with a joystick.

The article explains how the GNSS GPS L86-M33 module works and how to use it with an ESP32. It covers basic setup with an Arduino library, reading and decoding GNSS data over UART/I2C, and a portable GPS tracker project using an OLED display to show location, time, speed, and direction.

Build a DVI weather station using the Soldered NULA Max RP2350 and a BME280 sensor. Connect via Qwiic and DVI, install the required libraries, configure NTP time sync, read sensor data, and render graphs and a table on the display.

This article explains how PIR motion sensors work, what delay time means, and how to read DOUT/SOUT outputs. It includes an Arduino serial example and an ESP32 WiFi project that hosts a web page and sends an email alert when motion is detected.

This article explains what a breadboard is, how it is built internally, how to use it to connect components, and what its main advantages and limitations are.
