1602 Lcd Alphanumeric Character Blue LCD Display very commonly used in most embedded projects, the reason being its cheap price, availability and programmer friendly. Most of us would have come across these displays in our day to day life, either at PCO’s or calculators. The appearance and the pinouts have already been visualized above now let us get a bit technical.

1602 Lcd Alphanumeric Character Blue LCD Display very commonly used in most embedded projects, the reason being its cheap price, availability and programmer friendly. Most of us would have come across these displays in our day to day life, either at PCO’s or calculators. The appearance and the pinouts have already been visualized above now let us get a bit technical.

Although they display only text, they do come in many sizes and colors: for example, 16X1, 16X4, 20X4, with white text on blue background, with black text on green and many more. I2C Module has a inbuilt PCF8574 I2C chip that converts I2C serial data to parallel data for the LCD display. These modules are currently supplied with a default I2C address of either 0x27 or 0x3F.

These LCDs are ideal for displaying text/characters only, hence the name ‘Character LCD’. The display has an LED backlight and can display 32 ASCII characters in two rows with 16 characters on each row. 1602 Lcd Alphanumeric is named so because; it has 16 Columns and 2 Rows. There are a lot of combinations available like, 8×1, 8×2, 10×2, 16×1, etc. but the most used one is the 16×2 LCD. So, it will have (16×2=32) 32 characters in total and each character will be made of 5×8 Pixel Dots.

 

Specifications :-

  • Operating Voltage is 4.7V to 5.3V
  • Current consumption is 1mA without backlight
  • Alphanumeric LCD display module, meaning can display alphabets and numbers
  • Consists of two rows and each row can print 16 characters.
  • Each character is build by a 5×8 pixel box
  • Can work on both 8-bit and 4-bit mode
  • It can also display any custom generated characters
  • Available in Green and Blue Backlight

1602 Lcd Alphanumeric Pin Configuration

Pin No: Name: Description
1 Vss (Ground) Ground pin connected to system ground
2 Vdd (+5 Volt) Powers the LCD with +5V (4.7V – 5.3V)
3 VE (Contrast V) Decides the contrast level of display. Grounded to get maximum contrast.
4 Register Select Connected to Microcontroller to shift between command/data register
5 Read/Write Used to read or write data. Normally grounded to write data to LCD
6 Enable Connected to Microcontroller Pin and toggled between 1 and 0 for data acknowledgement
7 Data Pin 0  

 

Data pins 0 to 7 forms a 8-bit data line. They can be connected to Microcontroller to send 8-bit data.

These LCD’s can also operate on 4-bit mode in such case Data pin 4,5,6 and 7 will be left free.

8 Data Pin 1
9 Data Pin 2
10 Data Pin 3
11 Data Pin 4
12 Data Pin 5
13 Data Pin 6
14 Data Pin 7
15 LED Positive Backlight LED pin positive terminal
16 LED Negative Backlight LED pin negative terminal

16X2 Character LCD Pinout

 

  • GND should be connected to the ground of Arduino.
  • VCC is the power supply for the LCD which we connect the 5 volts pin on the Arduino.
  • Vo (LCD Contrast) controls the contrast and brightness of the LCD. Using a simple voltage divider with a potentiometer, we can make fine adjustments to the contrast.
  • RS (Register Select) pin lets the Arduino tell the LCD whether it is sending commands or the data. Basically this pin is used to differentiate commands from the data.
  • For example, when RS pin is set to LOW, then we are sending commands to the LCD (like set the cursor to a specific location, clear the display, scroll the display to the right and so on). And when RS pin is set on HIGH we are sending data/characters to the LCD.
  • R/W (Read/Write) pin on the LCD is to control whether or not you’re reading data from the LCD or writing data to the LCD. Since we’re just using this LCD as an OUTPUT device, we’re going to tie this pin LOW. This forces it into the WRITE mode.
  • E (Enable) pin is used to enable the display. Meaning, when this pin is set to LOW, the LCD does not care what is happening with R/W, RS, and the data bus lines; when this pin is set to HIGH, the LCD is processing the incoming data.
  • D0-D7 (Data Bus) are the pins that carries the 8 bit data we send to the display. For example, if we want to see the uppercase ‘A’ character on the display we will set these pins to 0100 0001(according to the ASCII table) to the LCD.
  • A-K (Anode & Cathode) pins are used to control the backlight of the LCD.
