PiCar-X v2.0 – IoT Smart Robot Car
An IoT smart robot car project built with a Raspberry Pi 4 and the SunFounder PiCar-X kit. It reads sensor data in real time (distance, line tracking, etc.) and publishes telemetry to the cloud using MQTT (Adafruit IO). The goal is to combine embedded systems + networking to create a responsive robot platform with remote monitoring, automation, and data logging.
