Supply voltage; 5V 4. The command register stores the command instructions given to the LCD. My board version is 1. A command is an instruction given to LCD to do a predefined task like initializing it, clearing its screen, setting the cursor position, controlling display etc. At the product description it said that the controller is HD Hello I am just dealing with the same problems, except mine show some squares 1620a the screen.

1602s is a 3. I followed the initializing sequence in the datasheet, but all I get is one line of white full rectangles. Any help with how to wire this up would be awesome. Adjust the potentiometer until the row of boxes is visible, but dim. Here is the datasheet for this screen. datassheet

Virgin Galactic — Commercial Space Flight. JoeO Full Member Posts: The LCD looks like this:. Worked on my first attempt.

In the next few steps we’ll connect the display further to the Arduino to let the arduino communicate with the LCD screen and put some characters on it. Please post technical questions on the forum, not by personal message. I hope that helps! Plug the pot meter in the breadboard, somewhere left of the LCD display and connect the three pins. I am wrong or is it??

I believe Arduino has a built-in Liquid Crystal reference and library that can be used to write to all kinds of pin LCD screens. You will want to dataseet all of the data pins to something like this converter.

dahasheet These modules are preferred over seven segments and other multi segment LED s. The first thing that you’ll want to do on any hardware project is locate the relevant datasheet. If you do not get this behavior then it makes no sense to continue since no amount of programming will fix things. Hey kylefarrisThis looks like a good first project! It’s only only used to display your Gravatar image!

Chaul on Feb 02, It worked after I had resoldered the LCD’s pins.

On the other hand your soldering looks like it could use some improvement. Thinking back, there’s something about commands, wait times, and busy flags JoeO on Feb 01, About the author This post was writen by Johan van Tongerencreator of this website. I was trying other codes but could not get success. Selects command register when low; and data register when high. We can find the descriptions of what each of the signal pins do in the datasheet as well: Ming 26 July Very Good Tutorial!

I did not see it until I scrolled down to look at your answer, then I saw it. Works like an absolute charm! Click to learn more about internal structure of a LCD.

I am using only parts from the Arduino starter kit I got from Deal Extreme.

I’m really wanted to learn everything I can about the hardware aspects of microcontrollers especially and obviously the Tessel. It looks like your connections are OK, but I can’t be sure.

I suggest you try and get all of the LCD connections to look like the one at D5, nice and shiny with no holes. The LCD has 16 pin holes
