How To Interface 16x2 Liquid Crystal Display With Arduino Uno

Sometime you need to display senser data e.g Temperature senser or data received through serial communication onto the 16x2 LCD so in this post i will explain how to interface 16x2 LCD with Arduino Uno . First you need to know the pin description of LCD. Note: In my LCD figure 15th and 16th pin is missing because i used the proteus software for the LCD image but in practical you can connect the 15th and 16th pin with +5V supply and ground respectively. For code go to your Arduino IDE>File>Examples>LiquidCrystal>HelloWorld example.In this example we use 4-bit mode of LCD in which only 4 data pins(D4,D5,D6,D7) are used. In 8-bit mode all the data pins are used. Upload this code to the board and design the circuit as given below. Circuit Diagram Also read: How To Interface Push Button With Arduino Uno.

How To Interface Push Button With Arduino Uno

A Embedded system basically consists of three parts- Input Processing Unit Output Input section takes input data from the external environment it can be switch, tempreture senser, pressure senser, light senser etc. After this the processing unit like Arduino Uno process the data gives desired output. You can get the output with the help of led, lcd, motor etc. So here we will discuss how to interface switch with Arduino Uno and we will get output on led. There are two method to interface the switch with Uno one is using pull up resistor and another is using pull down resistor. Pull up or pull down resistor ensures that input to the controller settle at desired logic level. Pull up and pull down resistor keeps input to Arduino Uno at logic 1 and logic 0 respectively by default. You can use the pull up and pull down method using hardware. In the hardware method just connect one end of 10k resistance with switch and another end to ground or power to pull down or pull ...

How To Write Code and Upload It To Arduino Uno

In this post i will explain how to write a basic code of led blinking and upload it to Arduino Uno . First of all download Arduino IDE it is open source. Open it you will find two function already there void setup and void loop all the declaration of pins as input/output eg.pinMode(13,OUTPUT) and declaration of baud rate e.g Serial.begin(9600) or part of code that you want to run only once is defined under setup function and a part of code that you want to run again and again is defined under loop function. Below is the code of led blinking. Code- int led=13; // we have connected the led at pin 13 of arduino uno void setup() { pinMode(led,OUTPUT); //declaration of 13 pins as output pin } void loop() { digitalWrite(led,HIGH); /// it will set led pin at high state(1) delay(1000); // delay of one second digitalWrite(led,LOW); /// it will set led pin at low s...
