An ESP32, a few sensors, and MQTT are enough to build a useful monitoring device for a home, greenhouse, or small IoT system. In this project, the ESP32 reads temperature, air humidity, and soil moisture, then publishes the measurements to an MQTT broker over Wi-Fi. The same architecture can later be extended with …

When you build firmware for a microcontroller, you usually end up choosing between two patterns: the simple Arduino-style loop() or a full RTOS-based design. Both can work well, but they solve different problems. The Arduino super loop is easy to understand: run setup once, then repeatedly execute the same code in a …

Arduino.cc has announced the end of Mbed Platform Mbed's End and the Shift to Zephyr: Impact on Arduino and Beyond Arm's decision to discontinue Mbed in 2026 has sent ripples through the embedded systems community. One of the most significant impacts is on Arduino, which has relied on Mbed for several of its boards. …
