The IR sensor module monitors the surrounding area to detect objects approaching the gate. When movement is sensed, it transmits a signal to the Arduino Nano, which processes the input and triggers the servo motor. The servo motor then rotates the connected mechanism to open the gate, holding it open before automatically closing it after a short delay.

Safety Precautions
Ensure your 5V power source is stable and correctly wired to prevent short circuits on the Arduino Nano. Double-check all connections before applying power to avoid damaging the IR sensor or servo motor. When working with moving mechanical parts like gates and servos, keep fingers and loose clothing clear of the actuation zone.
