What is a buzzer? How does it work?

It is the electronic part that responds to us with a “beep” sound as an output. In this project, we enabled him to guide us by making different tones at different levels of proximity. What is Buzzer for detailed information and working logic? How does it work? why is it used? How many types of buzzer are there? I suggest you look at the article named.

What is the HC SR04 Ultrasonic distance measuring sensor? How does it work?

It is a sensor that measures our distance as input. Is there any obstacle in front of me in this project? If so, how far? What is Hc-rs04 Ultrasonic Distance Sensor for detailed information and Hc-rs04 Ultrasonic Mesafe Sensörü nedir ? Nasıl Çalışır? I suggest you look at the article named.
