The following Python code for a raspberry pi, I have added a temparature sensor which works, however, I also added a sound buzzer and an ultra sonic ranger. I would like to add the buzzer and the ultra sonic ranger such that when i move an object closer to the sonic ranger and the temperature changes the buzzer buzzes. how can i achieve this. and the led to blink everytime the buzzer goes off

Guidelines for distance

Ultrasonic Ranger Distance Buzzer value

<20cm 0

<20cm 15

<15cm 25

<10 cm 50
