I'm new to arduino (and electronics for that matter) but I have a hunch and want to start to use the computer board to do some experimentation using harmonics with electrical signal generation.
I've seen you can buy signal generator boards (although I don't know which one(s) to use) on aliexpress but I need to be able do the following:
- I need to be able to vary the frequencies and voltages of the signals programmatically, creating a looping effect for experimentation, is this possible?
- In order to combine 2 or more signals (to create the harmonics), how many signal generator boards will I need? And, how should I connect them together to produce harmonics effects?
- What do I need to avoid doing to avoid damage of the circuits?
Any help/advice will be greatly appreciated.
