code structure: header header provides information and can also contain code living with the lab 7

code structure: setup function setup function is executed only once at the start living with the lab 8

code structure: loop function loop function is repeated indefinitely living with the lab 9

code digital I/O functions: pinMode digitalWrite digitalRead pinMode(13, Output) prepares pin 13 for outputs of voltage living with the lab 10

digitalWrite(13, HIGH) sets pin 13 to a voltage that means “on” (five volts in this case) living with the lab 11 code digital I/O functions: pinMode digitalWrite digitalRead

delay(1000); tells microcontroller to do nothing for 1000 ms = 1 s code living with the lab 12 digital I/O functions: pinMode digitalWrite digitalRead

digitalWrite(13, LOW) sets pin 13 to voltage that means “off” or zero volts living with the lab 13 digital I/O functions: pinMode digitalWrite digitalRead code
