How connect 1602a to Arduino?
- First connect the ground of Arduino to the VSS of the LCD.
- Then connect the V0 of the LCD to the ground for full contrast.
- Then connect RW to the ground for selecting write mode.
- Then connect K , which is the ground of backlight LED also to the ground.
- Then connect the 5V of Arduino to the VDD of the LCD module.
How do I connect Arduino to monitor?
- Insert your LCD screen into your breadboard vertically such that each pin has its own separate line on the board.
- Insert your potentiometer in the same way.
- Connect 5v and GND from Arduino to the / – rails on your breadboard.
- Connect Pins 1 and 16 from the LCD screen to the negative power rail.
What is LCD1602?
LCD1602, or 1602 character-type liquid crystal display, is a kind of dot matrix module to show letters, numbers, and characters and so on. It’s composed of 5×7 or 5×11 dot matrix positions; each position can display one character.
How do I use Arduino IDE?

Does an LCD need a resistor?
On the vast majority of LCDs (including ones from Adafruit) the LCD includes a series resistor for the LED backlight. If you happen to have one that does not include a resistor, you’ll need to add one between 5V and pin 15.
What is a 3×4 keypad?
This keypad has 12 buttons, arranged in a telephone-line 3×4 grid. The keys are connected into a matrix, so you only need 7 microcontroller pins (3-columns and 4-rows) to scan through the pad.
How to interface lcd1602 with Arduino?
