We built a head-tracking smart headlight system inspired by fighter jets 🚁✈️. Here’s how it works: An MPU6050 IMU sensor detects head movements in real time. That motion data is sent from the master ESP8266 to the slave ESP8266 using the ESP-NOW protocol. The slave then drives a 9g servo motor to turn the headlight in the same direction as your head. The whole system runs on a 5V battery for portability. Everything is coded in the Arduino framework. So when you move your head, the headlight fol
