Digital I/O

• blink?: turn an LED on and off.
• invert?: use a pushbutton to control an LED.
• loop?: controlling multiple LEDs with a loop.
• switch?: turning an LED on and off with each button press.

Analog I/O

• analog_read_blink?: use a potentiometer to control the blinking of an LED.
• color_mixer?: control three LEDs with a potentiometer.
• smoothing?: smooth multiple readings of an analog input.

Communication

• color_mixer?: use potentiometers to set the background color in Processing.
• graph?: Processing graphs the value of an analog input.
• switch?: click in Processing to turn an LED on and off.
• dimmer?: move the mouse to change the brightness of an LED.
