    5Works as expected
    By James
    [[VIDEOID:5a0336ec9d2aab52e6ab15756ad73b2f]]I have been operating this at 3.3 V. It produces a quieter sound at a slightly higher frequency, but it otherwise seems to do fine with that. This video demonstrates how a sample buzzer sounds driven at 3.3 V with intervals of 5 ms, 10 ms, 20 ms, 50 ms, 100 ms, 200 ms, 500 ms, 1 s, and 2 s.

    5Works well as a discovery buzzer for quadcopters
    By Nafi
    Bought this to replace a discover buzzer that got bashed in on my quadcopter during a crash. These buzzers matched the dimensions and electrical characteristics of the one that came with my chassis kit (chinese-made ZMR250 chassis with power distribution board). Works just as well as the original, and it's nice to have back-ups for the next crash.

    5Works great, here's some more info and example code:
    By Frequent Amazonian
    Works great, I'll include some example code I found below. These are loud but they're not ear piercingly loud. Small enough to fit on a breadboard spanning 4 pins, with 2 pins between the lead and ground.

    Here's some code to get you started:

    // Buzzer example function for the CEM-1203 buzzer (Sparkfun's part #COM-07950).
    // by Rob Faludi
    // [...]

    void setup() {
    pinMode(4, OUTPUT); // set a pin for buzzer output

    void loop() {
    buzz(4, 2500, 500); // buzz the buzzer on pin 4 at 2500Hz for 500 milliseconds
    delay(1000); // wait a bit between buzzes

    void buzz(int targetPin, long frequency, long length) {
    long delayValue = 1000000/frequency/2; // calculate the delay value between transitions
    //// 1 second's worth of microseconds, divided by the frequency, then split in half since
    //// there are two phases to each cycle
    long numCycles = frequency * length/ 1000; // calculate the number of cycles for proper timing
    //// multiply frequency, which is really cycles per second, by the number of seconds to
    //// get the total number of cycles to produce
    for (long i=0; i < numCycles; i++){ // for the calculated length of time...
    digitalWrite(targetPin,HIGH); // write the buzzer pin high to push out the diaphram
    delayMicroseconds(delayValue); // wait for the calculated delay value
    digitalWrite(targetPin,LOW); // write the buzzer pin low to pull back the diaphram
    delayMicroseconds(delayValue); // wait againf or the calculated delay value
