Section 4.4 - Mini Project 3


Time for some sensor fun!

In this project, you’ll apply concepts learned in previous lessons to independently create a dynamic LED system based on distance readings from an ultrasonic sensor. The lesson starts with an introduction to the project, explaining how you’ll control the blinking frequency of an LED in response to distance measurements. Your task is to code the LED to blink faster as you get closer to the sensor and slower as you move farther away. This exercise reinforces your understanding of both the ultrasonic sensor and Arduino programming, encouraging you to experiment and refine your approach. By the end, you’ll gain deeper insight into real-time sensor integration and control in Arduino projects.
