Pizza Robot Circuit

Here is one way of doing a circuit to manage all the sensors and motors for the pizza robot.

At the bottom of this page there is a Diptrace file you can download which has all of the correct components in it. You will need to make all the wiring connections and then draw in the paths taken by all the tracks. A0 A1 A2 and A3 are the inputs for the line following sensors, The two four-way connectors with SDA and SCL on them are for the colour sensor and the compass (doesn't matter which is which) The one labelled servo is to connect a servo motor to deliver the pizza.
