Plug in your LDR Light Sensor into pin F 51 and F 53. Then connect a 10k resistor to G 51 and and G 46. Then a short wire from the ground rail to H 46. Then take a wire from the 5v pin on the Arduino to G 53. Then take a wire from digital pin 7 on the Arduino to H 51.
Now take a wire from the ground rail to I 40. Put a 330 resistor into H 40 and H 34. Take a wire from digital pin 1 on the Arduino to H 33. Since LEDs have positive and negative you will need to plug the longer end of you LED into G 33 and the shorter into G 34.
