I have one Arduino Nano. And I would like to use it to build a 4 channel signal generator. It should have one Frequency knob for each channel - I can use Analog Inputs for them. and 10k potentiometers. It has to output 4 independent Square waves and each of them can be sepparately controlled by a frequency knob.
I would like to take the signal from PWM compatible I/O-s if its wise to do so. (maybe it is not)
My background is poor. I have not build anything huge with Arduino. Some very simple projects O-scope, some LED blinkers, one channel signal generator and something like that.
The main reason why I am writing is to figure out if Arduino Nano can handle what I am planning and to find out if anyone has an idea how to complete it. Frequency will stay below 22kHz but it must achieve it in all the channels.
