Okay so to start I am at best an extremely amateur project maker. I like to solder and understand somethings about electronics but most of this is way over my head I think. I'm a middle school science teacher and was trying to make a project for my students to assemble a small circuit game where they would have a wire loop that passes around maze and when they touched the maze wire with the loop it would set off a light and a buzzer. I checked with some folks about my circuit and they said it would be fine. I knew nothing about how piezzo buzzers worked. My school approved the purchase and I now have 100 buzzers and I'm not sure how they work.
So the design was a 9V batter connected to a switch and then a buzzer and LED in parallel (The LED is 12v Rated off amazon). The circuit would then go into the maze wire, on the other end of the 9V i would have the loop wire that would complete the circuit when the students touched them together.
I bought these buzzers: https://www.mouser.com/datasheet/2/670/cpe-165-1310296.pdf
and had no idea I need oscillation in my power to make these work so the question I have to those more knowledgeable is there anyway for me to save this, it was a large purchase from my school so I can't ask them to buy more (if it's cheap enough I may be able to take it out of pocket for my mistake) but I'm not sure how to produce oscillation easily with a 9V DC power source.
Thanks for all of your help, I really don't want to tell my principal I wasted the money on the buzzers, and I think the kids would enjoy it more if it lit up and made sound (maybe not the parents)
