- LCD R/W pin to GND.
- LCD VSS pin to GND.
How connect Arduino with LCD to potentiometer?
Below is a step-by-step guide: Connect the 10K Ohm potentiometer (this potentiometer is used to control the contrast of the LCD). The middle pin of potentiometer is connected to the VO pin and the other two wires are connected to +5V and ground on the breadboard.
Do you need a potentiometer for an LCD?
No, it would not be correct to use a single resistor to replace a potentiometer. On an LCD the potentiometer is used to adjust the bias level of the LCD – that is the contrast. You need to use it to set a voltage between Vcc and Vee, which you feed into Vo. That is, a voltage somewhere between +5V and -5V.
How to turn on backlight on Arduino LCD 1602?
Connect K to GND and A to 3.3 V, and then the backlight of the LCD1602 will be turned on. Connect VSS to GND and the LCD1602 to the power source. Connect VO to the middle pin of the potentiometer – with it you can adjust the contrast of the screen display.

What does Rs mean on Arduino LCD 1602?
RS: A register select pin that controls where in the LCD’s memory you are writing data to. You can select either the data register, which holds what goes on the screen, or an instruction register, which is where the LCD’s controller looks for instructions on what to do next.
