LCD PANEL., MATRIX KEYPAD AND ARDUINO UNO

Hi, I'm a newbie in this. But just want to ask whether does C1602a-v1.2 LCD panel 16 x 2, Matrix Keypad 4 x 4 and Arudino Uno work together? Because I have a problem with this. Please help me.

They can, if you don't try to use pins for more than one device.

Because I have a problem with this.

But, I'm not going to tell you which LCD I have, how it is connected, how the keypad is connected, what code I have, or what the problem is. Well, good luck with that approach.

The text LCD will need 6 pins to control it (or 7 if you want to control the backlight).
The 4x4 keypad will need 4+4= 8 pins to control
You should not use the Serial pins 0 and 1 on the UNO for that hardware.

So 7+8+2= 17 pins have to be used with your hardware and Serial for debugging the sketch.

An UNO has 20 pins. So everything is fine and should work.
