Hi all,
I am trying to work out a self driven 3 wire piezo...
The circuit is very easy and I have attached it below...
The resistor values are 10k and 180k with an inductance of 60mH, while the circuit should work fine at +5V supply and the frequency for piezo is 3KHz.
Even though having all the information correct(I have seen this circuit work in same condition with same values of everything), My circuit seems to have lost its way somewhere and I am not able to troubleshoot it.
Please can someone point out where I could be going wrong???
I am not sure if my inductor is doing good, how to I test its condition??
Also if i remove the inductor and connect GND instead to emitter, the buzzer beeps but at very low output...
Thanks...
