LiquidCrystal HelloWorld example is missing R/W wiring instruction #402

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
What steps will reproduce the problem?
1. Wire up LCD as per HelloWorld.pde or 
http://www.arduino.cc/en/Tutorial/LiquidCrystal text instructions. 

What is the expected output? What do you see instead?

Expected output is "hello world!" etc. Actual output is default top 
line-blocks, bottom-line blank.

What version of the Arduino software are you using? On what operating
system?  Which Arduino board are you using?

0020 / OS X / Duemilanove

Please provide any additional information below.

The instruction "LCD RS pin to ground" should be added to HelloWorld.pde and 
http://www.arduino.cc/en/Tutorial/LiquidCrystal (note that the Fritzing and 
schematic on that page have the wire connected).

(Also, the page says "with it's wiper" rather than "with its wiper".)
