Puzzled me that the lightSensor reading was higher in the dark, but now I get it. I was trying other codes but could not get success. The itj is simple for all to understad and get started.
Dot Matrix LCD Display Module 16×2
Works like an absolute charm! 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: Did not specify resistor value?
But it works anyway! I put in a 1K resistor. I am using only parts from the Arduino starter kit I got from Deal Extreme.
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. This way you can solder wires to it, solder a connector on it, whatever you want.
I choose to solder the connectors to the back so I could press the LCD display on the breadboard. To do this, snap of a row of connectors 16 pieces and stick them short pin up trough the LCD display connectors. 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 breadboard.
Connecting the display and breadboard First you need to power the display and its backlight. Next up is the pot meter.
We use 16002a potmeter to set the contrast of the display. Finetuning gets a little harder because the range is bigger, but that’s no problem for this tutorial. Plug the pot meter in the breadboard, somewhere left of the LCD display and connect the three pins.
Of you don’t datashdet them, turn the pot meter slowly from left to right to adjust the contrast. You can finetune this setting when we’ve got characters on the display later.
If your display looks like this, you’re doing fine: 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.
