thank you for this clear explained , introduction to programming Arduino, learned a lotand looking forward for your next lessons.

Thx for your project.a view questions about the sketch: what is the function of the led?what does Speedsec and Turnradius do? they are declared as integer, and later on they are equal(Speedsec=Turnradius and Turnradius=0;), so they both are 0.They never change in the code,so they are 0 and stay 0??
