Scalextric Track

Scalextric Track

The scalextric with traffic control is an educational tool designed to teach people about some of the technologies behind today's traffic control systems in a fun and interactive way. It was built for an exhibit at the Royal Society Summer science exhibition. But it also pops up at other science outreach events like Science and engineering day at the University of Southampton.

You can watch the videos below which demonstrate how the system works on and early prototype.

The inductive loop sensors used in this set were made out of a coil of wire with 13 turns. This is connected to an amplifying circuit using LMC662CN Op-Amp. The circuit diagram is below. The traffic lights are three LED's red, yellow and green. The circuit for these is below also.

The inductive loop sensors and traffic lights are connected up to an Arduino micro-controller. The Arduino is programmed with the junction control logic. You can download the Arduino code here.
