display brightness

I just set up display.ino
after doing so it works but the display is very dim. it is display from starter kit LCM1602C. Any ideas how to make brighter?

setcontrast() ? From web_page:

Pin 3 is connected to the middle pin of the 10k potentiometer, and is used to adjust the contrast of the LCD.

Are you sure you have connected the power pins, pins 1 and 2? There have been reported cases of a display working, although dimly, without those connections.


If it looks ok from a different angle, not straight on, then it is the contrast pin.

Is the backlight powered?
