I am newby in Tikz and want to draw a circle with on it 16 circle-shaped nodes.
Each slide increment would shift to the next node rightward or leftward ( an example with both should be fine), while highlighting it (the highlight should be about the current position/node).
Anybody could help me achieving this ?
An example of the drawing is attached :

Thank you

EDIT : This is a good start but i need circle shaped nodes not text with one node each time hightlighted (colored with blue) (the current position) and node shift could be right or left :

documentclassreport
usepackagetikz,calc

begindocument
begintikzpicture
foreach a in 1,2,...,17
draw (a*360/17: 4cm) nodeangle a;

endtikzpicture
enddocument

I think something like this is what you're after.

documentclassbeamer
usepackagetikz
% define a counter
newcountCircNum
% macro to hold a color name
newcommandClrblack
begindocument
beginframe
% set up an animation, CircNum changes from 1 to 17
% with each frame
animatevalue<1-17>CircNum117
begintikzpicture
% draw the main circle
node [circle, draw, minimum size=8cm] (c) ;

foreach a in 1,2,...,17
 % if a is equal to CircNum, set the color to blue
 % otherwise set it to black
 ifnuma=theCircNum
 renewcommandClrblue
 else
 renewcommandClrblack
 fi
 % make a new node for the small circles
 node[Clr, % with the color defined by the macro
 draw, thick, % draw the outline
 fill, % fill it
 minimum size=5mm, % set the size
 circle, % circular shape
 label=[Clr]a*360/17+180:a % add the number on the inside
 ] at (c.a*360/17) % position it on the edge of the main circle
 ;

endtikzpicture
endframe
enddocument

Here are the first three slides of the PDF:

Welcome to TeX.SE!

Here is a solution that borrows int_step_variable:nnnNn from expl3:

 % The big circle
 node[circle, minimum width=2*bigcircleradius, draw] (C) ;

 % The small circles and their labels

 pgfmathsetmacroangle90 - i*360/nsteps
 pgfmathsetmacroothersideangle+180
 pgfmathsetmacroiplusoneint(i+1)
 pgfmathsetmacroiplustwoint(i+2)

 uncover<iplustwo-> 
 node[circle, draw, minimum width=2*smallcirclewidth,
 label=otherside:iplusone] at (C.angle) ;
 
 uncover<iplustwo> % fill one small circle per frame
 node[circle, fill=red!20, minimum width=2*smallcirclewidth]
 at (C.angle) ;
 
 

endtikzpicture
endcenter
endframe

enddocument

Note: as an alternative to the following code:

pgfmathsetmacroiplustwoint(i+2)

(...)

uncover<iplustwo-> (...) 
uncover<iplustwo> (...) 

one could use, assuming e-TeX extensions are available:

uncover<thenumexpr i+2relax-> (...) 
uncover<thenumexpr i+2relax> (...) 

Now, let's redo the same beamer presentation, but using a more straightforward order (small circles at angles 1*360/10, 2*360/10, ..., 10*360/10 degrees, respectively). The main code is written in a (slightly) different way from the previous example: it uses two loops and the pause macro from beamer, whereas the first example did everything in one loop, and used only uncover.
