My project uses a Duemilanove connected to an opto isolator and a FET.
What i would like to do is connect the output to various transformers and loads then tweak in the frequency and duty cycle to give me optimum performance. Some of the transformers i will be using a ferrite with various spacer’s and the cap and load on the output can change the resonant frequencey quite a bit so i would like to be able to compensate for this.
Has anyone got any suggestions as to how It would be best to do this? I had thought about using Tone but this would not allow me to adjust the duty cycle.
