Hello, I connected my arduino to an LCD 1602 and it was working fine, but then when I took out the pins VO(pin for contrast) and pin A(pin for backlight) and plugged it in again the arduino wasn't working.
Please help.
It's not a good idea to change wiring with the power on - is that what you did?
Try using the Arduino without the LCD, just blink or something that prints to serial so you can ascertain whether the Arduino itself is broken.

What do you mean by "wasn't working"?
Is it working now?
Can you upload the "blink" sketch?
Thanks.. Tom..
