Good luck! (I am also a beginner but got the hang of it pretty quick. Type up the code again (Python) and see what happens, and then play around with it. buzzerPin = "insert pin number here") You can refer to the code I put below along with the circuit picture. I hope this helps! Also in your code, you need to define which pin the buzzer is in (the GPIO pin, if you were to google a numbered version it should let you know which pin to write ex. The frequencies are changing as the program runs thus allowing it to make a siren-like sound. The following is code for something that sounds like an alarm. In order to change the frequencies, you would have to change your code. It doesn't exactly matter what GPIO pin you plug it into to control the frequencies. When you want to make different sounds I would recommend using a passive buzzer. Basically, I need two functions - a sound for when they get it right, and a sound for when they get it wrong. Viewed 6k times 0 I have a multiple choice question game, and Im wondering how to hook up a piezo buzzer to make a sound when someone puts in an answer. Ask Question Asked 4 years, 8 months ago. An active buzzer has only one frequency, and normally has a water proof coating at the bottom. Different Frequencies with Piezo Buzzer - Python. Passive buzzers are the ones on which you can control the frequencies, thus making it ideal for coding songs. So there are two types of buzzers, active and passive.
