I have a great idea where I want to design a car parking lot such that anytime a car departs from the parking lot , a sensor picks the action and sends the signal to the microcontroller to display where the car is located. Let me post this questions;
1. if i settle for the infrared or the ultrasonic sensor what are the factors that i should consider before making the choice of using them?
2.with me is the 16f877a which i want to use to connect the sensor, can i get some help on how i should do the connection? (If possible a schematic would work in the best way).
3. can you suggest the cheapest infrared sensor or detector that i should use.
