Exploring the Nucleo L476RG Board with the STM32 Microcontroller
An introduction to the STM32 Nucleo L476RG platform for rapid prototyping: pinout, Arduino compatibility, and how to get started developing firmware with STM32CubeIDE.
Environmental Monitoring with STM32 Nucleo L476RG and DHT22: A Practical Guide
A practical guide to building an environmental monitoring system using the STM32 Nucleo L476RG and the DHT22 sensor. Temperature and humidity readings with a real-time OLED display.
Environmental Monitoring with DHT22, ESP32 and InfluxDB
A complete environmental monitoring system: an ESP32 collects data from the DHT22 and sends it via MQTT to InfluxDB, with visualization on Grafana dashboards. A lightweight, efficient architecture.
SBC vs. SBM: Differences Between Single Board Computer and Single Board Microcontroller
A direct comparison between SBCs and SBMs: understand when to use a Raspberry Pi versus an Arduino, and how that choice impacts your project’s cost, power consumption, and complexity.
Connecting the SIM7600G to the Arduino Mega
Bench notes on integrating the SIM7600G LTE modem with the Arduino Mega: wiring, AT commands, and first steps toward cellular connectivity in IoT projects.
Arduino Mega 2560 + SIM7600G: Cellular IoT Node with JSON Telemetry
A complete cellular IoT node: an Arduino Mega 2560 + SIM7600G collects network, GPS, and modem statistics, packs them into JSON, and publishes via MQTT. For field operations without Wi-Fi.
