Basic skills to practice:
Correctly stripping wire
Using Solderless breadboards
Wire color-codes: Black= GND, Red= Power, colors=signals
Transistor and Breadboard Potentiometer terminals
Below: Terminal strip enables motor connections to be revised easily to control direction of motor, and to control which photocell controls which motor:

Wires are kept as short as possible- neatness matters!
