i have an Arduino Uno board.I got a JHD162A LCD which is connected with an ATMEL chip (AT 89C 2051)
So i got 3 wires to connenct on Arduino...
1)GND
2)+5V
3) Pin1 (X) on the DIGGITAL inputs...
After these,the LCD prints scrolling numbers all time.
Can you help me find what's wrong?

The AT89 chip is probably a part of an LCD backpack to run the LCD on one TTL serial line. Do yo have a manual of the thing? You need to know the baud rate to communicate with it and the commands to control the LCD.
It's OK with the connection and the communication.Thank you for responding! 8)
I want to ask something else...
I'm working on a line follower robot..so,i need that LCD to print some time measurements (for example,how many seconds did the right/left motor worked).Two time counters.
Do you know how can i do that?
