My Arduino project is a level indicator that uses a Piezo transducer.
I've used the "tone" function to manipulate the sound to raise the pitch when the desired level is reached.
With the 'tone' function I can very precisely control the pitch and speed of the speaker.
However, the project runs...
Hello! I am an absolute beginner learning electronics by working my way through the Make:Electronics book by Charles Platt. I have a long way to go, so I am hoping someone can give me some guidance on a project I am working on now.
I would like to have 4 small piezo microphones independently...
I want to drive piezoelectric transducer with resonant frequency 110khz and input voltage 70 volts ac with arduino. I generated a square wave of same frequency with arduino than converted it into ac voltage using RC filter than for the step up I used transformer small getting amplitude of 67...
