Process

This project is composed of four main components: a bend sensor, a photoresistor, a LED, and a buzzer. The bend sensor operates within a range of 150 to 500, while the photoresistor functions in a range of 2000 to 4000. When the bend sensor value is solely below 250, the LED will light up for 1.5 seconds and then turn off for 0.5 seconds. Conversely, when only the photoresistor value falls below 100, the LED will be on for 0.5 seconds and off for 1.5 seconds. If both values are below their respective thresholds, the buzzer will be activated and start beeping.
