2*16 JHD LCD


SKU: PE - 127 Category: Tag:


16×2 Character LCD – Black on Green is a 16 characters wide, 2 rows character LCD module. It utilizes industry-standard controller, works in 4/8-bit parallel interface. Display area is LED back-lit in yellow color.

A Liquid Crystal Display ordinarily condensed as LCD is essentially a presentation unit constructed utilizing Liquid Crystal innovation. At the point when we fabricate reality/genuine hardware based undertakings, we need a medium/gadget to show yield esteems and messages. The most essential type of electronic showcase accessible is 7 Segment show ? which has its own impediments. The following best accessible choice is Liquid Crystal Displays which comes in various size particulars. Out of all accessible LCD modules in market, the most generally utilized one is 16?2 LCD Module which can show 32 ASCII characters in 2 lines (16 characters in 1 line). ?LCD modules structure a significant part in numerous arduino based implanted framework plans. So the information on interfacing LCD module to arduino is exceptionally fundamental in planning implanted frameworks. This segment of the article is tied in with interfacing an Arduino to 16?2 LCD. JHD162A is the LCD module utilized here. JHD162A is a 16?2 LCD module dependent on the HD44780 driver from Hitachi. The JHD162A has 16 pins and can be worked in 4-bit mode (utilizing just 4 information lines) or 8-digit mode (utilizing each of the 8 information lines).

RS pin of the LCD module is associated with computerized pin 12 of the arduino. R/W pin of the LCD is grounded. Empower pin of the LCD module is associated with computerized pin 11 of the arduino. In this undertaking, the LCD module and arduino are interfaced in the 4-cycle mode. This implies just four of the computerized input lines( DB4 to DB7) of the LCD are utilized. This technique is extremely basic, requires less associations and you can nearly use the maximum capacity of the LCD module. Computerized lines DB4, DB5, DB6 and DB7 are interfaced to advanced pins 5, 4, 3 and 2 of the Arduino. The 10K potentiometer is utilized for changing the difference of the presentation. 560 ohm resistor R1 limits the current through the backdrop illumination LED. The arduino can be fueled through the outside force jack gave on the board. +5V needed in some different pieces of the circuit can be drawn from the 5V source on the arduino board. The arduino can be likewise controlled from the PC through the USB port.


// include the library code:


// initialize the library with the numbers of the interface pins

LiquidCrystal lcd(7, 6, 8, 9, 10, 11);

void setup()


// set up the LCD’s number of columns and rows:

lcd.begin(16, 2); // Print a message to the LCD.

lcd.print(“TechPonder”); }

void loop()

{ // set the cursor to column 0, line 1 // (note: line 1 is the second row, since counting begins with 0): lcd.setCursor(0, 0);

lcd.print(” TechPonder “);


lcd.print(” Arduino LCD “);
