Fading Demonstrates the use of the analogWrite() function in fading an LED off and on. AnalogWrite uses pulse width modulation (PWM), turning a digital pin on and off very quickly, to create a fading effect. The Circuit Connect the anode (the longer, positive leg) of your LED to digital output pin 9 on your Arduino through a 220-ohm resistor. Connect the cathode (the shorter, negative leg) directly to ground. /*  Fade  This example shows how to fade an LED on pin 9  using the analogWrite() function.  This example code is in the public domain.  */ int brightness = 0;    // how bright the LED is int fadeAmount = 5;    // how many points to...

LiquidCrystal - autoscroll The Liquid Crystal Library allows you to control LCD displays that are compatible with the Hitachi HD44780 driver. There are many of them out there, and you can usually tell them by the 16-pin interface. This example sketch shows how to use the autoscroll() and noAutoscroll() methods to move all the text on the display left or right. autoscroll() moves all the text one space to the left each time a letter is added noAutoscroll() turns scrolling off This sketch prints the characters 0 to 9 with autoscroll off, then moves the cursor to the bottom right, turns autoscroll on, and prints them again. Hardware RequiredArduino Board LCD Screen (compatible with Hitachi HD44780 driver) 10k Potentiometer breadboard hook-up...
