It can be set as an input, output, or an input with an internal pull-up resistor. */ Control Structures if(condition) { // if condition is TRUE, do something here } else { // otherwise, do this } for(initialization; condition; increment) { // do this } /* The ‘for’ statement is used to repeat a block of statements enclosed in curly braces. An increment counter is usually used to increment and terminate the loop. */ Digital I/O digitalWrite(pin, val); /* val = HIGH or LOW write a HIGH or a LOW value to a digital pin. */ int var = digitalRead(pin); /* Reads the value from a specified digital pin, either HIGH or LOW. */ Analog I/O analogWrite(pin, val); /* Writes an analog value to a pin. val = integer value from 0 to 255 */ int var = analogRead(pin); /* Reads the value from the specified analog pin. */ Advanced I/O tone(pin, freq); /* Generates a square wave of the specified frequency to a pin. Pin must be one of the PWM (~) pins. */ tone(pin, freq, duration); /* Generates a square wave of the specified frequency to a pin for a duration in milliseconds. Pin must be one of the PWM (~) pins. */ noTone(pin); // Turns off the tone on the pin.
