/*
* To use this sketch, connect the eight pins from your LCD like thus:
*
* Pin 1 -> +3.3V (rightmost, when facing the display head-on)
* Pin 2 -> Arduino digital pin 3
* Pin 3 -> Arduino digital pin 4
* Pin 4 -> Arduino digital pin 5
* Pin 5 -> Arduino digital pin 7
* Pin 6 -> Ground
* Pin 7 -> 10uF capacitor -> Ground
* Pin 8 -> Arduino digital pin 6
*
* Since these LCDs are +3.3V devices, you have to add extra components to
* connect it to the digital pins of the Arduino (not necessary if you are
* using a 3.3V variant of the Arduino, such as Sparkfun's Arduino Pro).

You can’t perform that action at this time.
