Arduino for Beginners - 2022 Complete Course - Step 2 - Change LED Blink Rate Depending on the Distance

The tutorial guides on making a yellow LED blink as a warning light, with its blink rate determined by the distance measured from an ultrasonic sensor. It covers setting up the LED, initializing necessary variables, creating functions to toggle the LED and adjust its blink rate, and optimizing the code using one-line if statements. The tutorial concludes with testing the setup to ensure the LED blinks faster as the object gets closer to the sensor.
