Model of smart street lighting

The work consists of 4 LEDs, an LCD screen, 2 ultrasonic sensors and a 7-segment indicator. The 7-segment indicator counts down from 9 to 0 for the duration of the lighting, changing the state of the LEDs, i.e. they turn on or off when the countdown ends. Ultrasonic sensors measure the distance to the object and as it approaches, the LEDs turn on and off in turn. The model represents smart street lighting in 2 directions of movement, and if there are no pedestrians, the lighting is turned off. This saves electricity. The LCD screen shows the time of day and whether the lighting is on or off.
