Program Skeleton
Basic Commands in Arduino IDE
delay(value
): waits a noted amount of time before moving on to following commands
●value: a number denoting time in milliseconds (1000 milliseconds = 1 second)
digitalWrite(variable
, setting
): sets a component to on (HIGH) or off (LOW)
●variable: name of the component
●setting: Either HIGH or LOW
digitalRead(variable
): returns the value of a noted component, either HIGH or LOW
●variable: name of the component
analogWrite(variable
, value
): sets a component to a certain value from 0-255
●variable: name of the component
●value: A number 0-255
NOTE: can only be used when a component is plugged into a pin with ~symbol
analogRead(variable
): returns the value of a noted component, a number 0-255
●variable: name of the component
NOTE: can only be used when a component is plugged into a pin with ~symbol
Variables & Functions
int variable
= value
: creates an integer variable and assigns it a value
●variable: name of the variable written in camelCase
●value: A whole number (positive or negative)
void function
(){}: defines a function as the commands found between the curly braces that will not return a value
●function: name of the function, written in camelCase
●To call the function, simply write the function name and a set of parentheses, ie. myFunction();
●Parameters can be included in the parentheses
