I want to create sine waves from 0.1Hz to 10Hz which are controlled from a software. For that I thought I can use micro controller as an interface between the PC and the sine wave signal.
But if I can be able to change the uC's frequency of the pulse train, how then I can convert those pulses to sines? Im not after high precision.
Is using RC filter recommended for such range and what RC values would be fine? The frequency range will be 0.1Hz to 10Hz. Or is there more practical or bulit in solution?
