I'm a new member of the raspberry pi community and I have problems with starting my first project. I want to be able to create a data signal using pulse width modulation with the gpio headers. The duty cycle would determine the value of a bit. so for example 75% duty cycle would represent a 1 and a 25% duty cycle would represent a 0. So I have to be able to control the amplitude of the signal very precicely since I want the frequency of the signal to be around 10000 hertz. The data signal would be used to control a LED strip. I want to write the software from the ground up. How would one go about this? I know python and a little bit of c++.
