For one of my projects I was required to draw a circle using the pen(beginner stuff). I wanted to draw a  simple circular spiral that stopped when the sprite hit the edge  but was not sure how I should go about it.

If you want a spiral, you'll need a variable.  Try this:

when I receive [Circle  v]
set [variable  v] to (1)
pen down
repeat until <touching [side  v]?>
move (variable) steps
turn cw (1) degrees
change [variable  v] by (1)
end

Thanks, I'll see how this one goes.

I hope it works!  You'll probably need a number higher than 1 for the rotate block, though...

try making the rotate block 10 

spirals are easier if you use polar co-ordinates (radius,angle) this demo will draw you an archimedean spiral
