This applet illustrate relation between normal force and friction force.
You can change the angle θ to find out how normal force/friction force varies with angle.

Normal force N= m*g*cosθ
If  m*g*sin< μ N , friction force f=m*g*sinθ
otherwise  friction force f=μ N = μ*m*g*cosθ
where μ is static friction coefficient.
μ N is the maximum static friction force when the normal force equal N.

found this

but their 2 friction applets didn't load in my browser properly, their others applets are okay.
