QUESTION 2 Referring to the timing chart and Circuit diagram in Figure Q2-1 and Q2-2. Fill blanks in Arduino code and explain function of the system. Figure Q2-2 This is example code for TEST *1 setup()\{ pinMode( 8 , pinMode (9,); pinMode (12, pinMode (13, \} loop()\{ if ( digitalRead (12)== LOW \{ delay(1000); digitalWrite( 8 , _ _ ); digitalWrite (9, if ( digitalRead (13)= delay(1000); digitalWrite( , LOW); digitalWrite( , HIGH); \} if (digitalRead( ()=HIGH){ digitalWrite (8, digitalWrite( 9 , \} \} Explain the function
