user15851: so I have a circuit with a buzzer and a resistor:

This circuit should be working, but for some reason the buzzer doesn't sound. I pushed the buzzer into the breadboard as hard as I could, I put the + side to positive and the - side to negative but it still doesnt work :(. How can I fix this?
Quick curiosity question: When I was doing electricity in school, the teacher just called the buzzers 'buzzers' but when I started doing arduino I noticed that the arduino community seems to call them 'Piezo buzzers/piezo speakers'. Is there any significance in the word 'Piezo' and should I start referring to them as 'Piezo buzzers' myself?

user25643: There is two kinds of buzzers - active and passive

Passive buzzer means they can be operated by applying  just logic high to + and low to ground.

Digitalwrite function will do this job

Active buzzers needs pulses to make sound. Sound produced depends on the frequency.  Your buzzer might be a passive one. You can make a symphony by applying different frequencies..

'tone' function will help you for this
