I am using only parts from the Datashee starter kit I got from Deal Extreme. Of you don’t see them, turn the pot meter slowly from left to right to adjust the contrast.

New on Dreamdealer Behind the scenes: Your mail is safe with me. Puzzled me that the lightSensor reading was higher in the dark, but now I get it.

Next up is the pot meter. Just mention the resistor value for the light sensor again when you deal with it, it is mentioned in the beginning,but I missed it first time around,excellent tutorial: Also there are many different versions of the LCD display with different pinouts and I couldn’t really find which the DX version exactly was.

About the author This post was writen by Johan van Tongerencreator of this website. Finetuning gets a little harder because the range is bigger, but that’s no problem for this tutorial. Vasilis 03 December you made my day. Did not specify resistor value?

Kevin 04 September Works like an absolute charm! If your display looks like this, you’re doing fine: CSS-only Clock Intelligent image cropping with focal point image-rendering: Connecting the display and breadboard First you tim to power the display and its backlight.

Ming 26 July Very Good Tutorial! This website is his personal playground which changes almost every day. Plug the pot meter in 6102a breadboard, somewhere left of the LCD display and connect the three pins.

Connecting a A LCD display and a light sensor to Arduino UNO • Dreamdealer

To do this, snap of a row of connectors 16 pieces and stick them short pin up trough the LCD display connectors. Basil 05 April Thanks a lot for the explanation, Great work! It’s datasbeet only used to display your Gravatar image! This way you can solder wires to it, solder a connector on it, whatever you want. Moses Lakra 04 November A good tutorial.


Stick the LCD display in the breadboard, somewhere on the right in the lowest row of holes so you can connect the breadboard wires above and the display rests on the unused rows of the daasheet. I choose to solder the connectors to the back so I could dstasheet the LCD display on the breadboard. Michael Bean 14 December Excellent!!! I was trying other codes but could not get success.

But it works anyway! You can finetune this setting when we’ve got characters on the display later. We use the potmeter to set the contrast of the display.

The ifm is simple for all to understad and get started.

Worked on my first attempt. Frank M 25 April Did not specify resistor value? Works like an absolute charm! 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. I put in a 1K resistor.
