I've been trying to drive a piezoelectric transducer to form a mist from a body of water. I bought the transducer from audiowell and basically is just a high frequency speaker.
I'm using a 555 timer that can operate at 2mhz. I started by getting a frequency of 16hz and connected the 12 volt source to a pc speaker. When the circuit was closed it gave a buzz. After this it appeared everything worked and I replaced the speaker with the transducer but got nothing. I changed the resistors and capacitors to get a higher frequency but still nothing.
Is there anyway to test the transducer? I tested for connectivity, resistance across the terminals but its possible these don't apply to the transducer.
