Infrared line tracker modules hardly need an in-depth explanation as they’re very familiar to most electronics and robotics hobbyists. In this post I’ll discuss a popular and cheap infrared line ...

This project is like a wireless communication system where one device (the transmitter, an Arduino Nano) sends location data (GPS coordinates) or a test message ("Namaskaram") to another device (the ...

Combining the dual-core processing capabilities of the ESP32 with the reliability of GSM connectivity, the ESP32 GPS tracker with SIM800L is the perfect solution for real-time position tracking.

I needed a multichannel line tracker sensor module for an upcoming project. A quick search found several versions of infrared line tracker sensor modules that met or exceeded my demands, but I picked ...

Autonomous dual-axis solar tracker using actuator & stepper control, GPS/compass input, and SunPy-based sun positioning. Features Raspberry Pi–Arduino communication, MQTT/HTTP protocols, and a ...
