Hello,
I was wondering if there was a way to create a relatively high frequency sine wave (5-6 kHz) from a DC input. I am working on a project where the user needs to locate a remote object by pressing a button on his/her bracelet. My idea was to use an RF transmitter and receiver. The receiver output is then connected to a piezoelectric speaker which guides the user to the object. The one problem is that I don't know how to convert a DC input to a sine wave. Also, two constraints: since the bracelet is going to be worn, it cannot be too big and no microcontrollers (nature of the project).
Thank you,
Hazal
