Build Plant Watcher with the Soldered DeepSleep NULA ESP32-S3 to monitor light, soil moisture, temperature, and humidity. Read multiple sensors, send the data as JSON over WiFi to a webhook, trigger low-soil alerts, and use deep sleep for efficient battery powered operation.

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.

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 shows how to build a simple DIY smartwatch using the NULA Mini and an SSD1306 OLED display, explains the hardware, interface logic, time and weather features, and overall project structure.
