Parking Pass

Hello, my name is Bhavraj. For my final engineering project, I will be working on developing a parking pass system. This project will involve using key components such as distance sensors to detect vehicles, a 7-segment display to provide visual feedback, and a servomotor to control movements like opening or closing a barrier. My objective is to design an efficient and functional system that can effectively manage parking access.

1. 330 Ohm Resistors to LEDs:

• Connect 330-ohm resistors from the power rail (positive) to the cathode (positive leg) of both LEDs.

2. Capacitors to Resistors:

• Connect the cathode (positive leg) of both capacitors to 10 kΩ resistors, which should also be connected to the power rail.

3. Capacitors to LEDs:

• Connect the anode (negative leg) of both capacitors to the anode (negative leg) of the LEDs.

4. LEDs to NPN Transistors:

• Connect the anode (negative leg) of the LED to the collector pin of the NPN transistors.

5. Capacitors to NPN Transistors:

• Connect the cathode (positive leg) of the capacitors to the base pin of the NPN transistors.

6. NPN Emitters to Ground:

• Connect the emitter pin of each NPN transistor directly to the ground (negative rail).
