In this video, I demonstrate how to create and install a blue LED dot matrix display on a car's rear window using an ESP32 and Bluetooth control. This setup displays "BRAKE ON!" and "REVERSE!" messages based on relay triggers and allows for custom messages via an Android app. Watch the full video for step-by-step instructions, including designing a 3D printed casing and using suction cups for easy installation.
