This project demonstrates how to build a real-time GPS tracker using the Heltec WiFi LoRa 32 V4 and the REYAX RYS352A GNSS module. The tracker hosts its own web interface, allowing any device on the same Wi-Fi network to monitor live location and travel history directly from a browser. The project processes NMEA data locally, displays live coordinates on the onboard OLED, and visualizes the current location and travelled path on OpenStreetMap without relying on cloud services.

In this project, we will build a Smart Weather Monitoring System using the ESP32-S3 Smart Display, BME280 sensor, Rain Sensor, and LDR sensor.

In this project, we will interface a 0.96-inch SSD1306 OLED display with Arduino using both I2C and SPI communication methods.

In this project, we will build a long-range wireless appliance control system using an Arduino Nano and the RYLR999 LoRa + BLE module.

In this guide, you’ll explore how L293D Motor Driver shield works and how to use it with an Arduino UNO to control DC motors, servo motors, and stepper motors.
