Manipulate parameters/constants in a set of differential equations?

Hello there,
just in advance, I am relatively new to Mathematica.
I have a set of coupled differential equations that I have already solved using ‘NDSolve’. In these equations, Parameters like ‘M’ or ‘l’ occur. Now I want to vary these Parameters with a slider or something, in order to observe what happens. Similar like this example of ‘Manipulate’:

Manipulate[Plot[Sin[a x], {x, 0, 10}], {a, 0, 10}]

Have you got any idea how to approach this problem?

Thank you very much for your help!

A Google search for “mathematica manipulate ndsolve” shows several examples of how to do this.
