cgoodger 1:fb4ff3d2b5d0 1 //Amalgamation of Project_Test_1 and Project_Test_2_switch codes to check viability of a simple 1/2 switch light interface.
cgoodger 1:fb4ff3d2b5d0 2 //Expansion of Project_Test_1 protocol to include three more pins and two more traffic light circuits.
cgoodger 1:fb4ff3d2b5d0 3 //Project_Test_8_Switchtest2 amalgamated to provide switch command to light circuit
cgoodger 1:fb4ff3d2b5d0 4 //the code checks if the value of X has changed from 0 to 1 at the end of the code turning all lights to red for 10 seconds before-
cgoodger 1:fb4ff3d2b5d0 5 //returning the value of X to 0 to continue the normal lights sequence. X remains 0 unless button is pressed.
cgoodger 1:fb4ff3d2b5d0 6 //Normal light sequence being that the lights cycle through a red, yellow, green loop at prespecified time intervals.
cgoodger 1:fb4ff3d2b5d0 7 //Lights act in opposite pairs to reduce pin number and to cimpify code.
