I have an unknown brand LCD with 18 pins.
No datasheet, no manual , no model number.
The LCD is currently connected to it's original device and it's displaying some information.
The device works with 9V, when the device is powering up, pins 1 and 17 seem to be GND and VCC ( 9V ).
I need someone to help me write custom information on the display.
I have an arduino UNO at home also.
