I want some ideas, how can i make project using circuito.io
You mean a system that detects when the parking slot is empty or one that parks your car in an empty slot? It’s important to understand what you want to build and define the functionality before you get started.
If it’s the first option, you can start with a simple circuit using an ultrasonic sensor to detect the presence of a car, and some LEDs or other indicators that the slot is free. Here’s a link to get you started - https://www.circuito.io/app?components=512,10820,11021,13959.
Later on you can add a connectivity device to send updates to your phone.
If you have anymore questions, let us know.
