squishy circuits question
I am using conductive dough to teach circuits to preschoolers. I ordered a 4 AA battery pack and some blue Led's which work great with the dough. But I also ordered large wire Piezo #1739 buzzer which doesn't work. Are 6 volts not enough volts? Which buzzer would work in this set up? Could you give me an order number? Thank you!

Re: squishy circuits question
PID 1739 is not a buzzer, just a piezo element. To make sound you would need to feed it a square wave signal for a buzzer this is what you would want. https://www.adafruit.com/products/160 You probably could get a buzzer at Radio Shack too.
