The motors should appear to be driving the same axle. Next, attach a wheel to each of the two DC motor shafts; now attach the two remaining wheels to the non-motorized (imaginary) axle of the car.
Place the breadboard inside the chassis of the car, and assemble the Photon, the L293D motor driver IC, the Li-Po battery, and the 3-6V DC power supply on the breadboard. Now you should make the connections using the jumper wires as per the following connection diagram:
In this connection diagram, the ground (GND) connections are omitted for clarity. In actual practice, all GND pins need to be connected together, and this common ground point needs to be connected to the negative...
