Ultrasonic automatic sensing barrier DIY kit

The ultrasonic automatic induction gate barrier machine intelligent hardware DIY kit is produced using the A.rduino nano development board. The vehicle’s automatic induction gate opener is mainly used to learn nano development boards, ultrasonic sensors, buzzers, four-digit digital tubes, and light-emitting diodes. It is also compatible with the A.rduino IDE development environment.

The main function:
Functional version: When a vehicle enters, the ultrasonic sensor senses, and the steering gear rotates to open the gate.
Enhanced version: Based on the functional version, the calculation of the remaining number of parking spaces is added, and there will be a green light flashing and a buzzer prompt when passing.
When the remaining parking space equals 0, the gate will be prohibited from opening when a car enters, a red light will flash, and a buzzer will prompt.
