How to make a graphical thermometer using arduino & nokia 5100 LCD

It is simple arduino  thermometer project

You Need--

Arduino UNO or any other arduino board

Nokia 5100 LCD Module

Analog Temperature sensor LM-35

Jumper wires

Bread board or vero board


here I use nokia  pcd 8544 - 1.4.3 library ( download library )

after add library You can get code in sample of 8544 library

                                               Schematic of this project

How to Decode any IR remote ( TV,DVD,AC any other)

Decoding IR remote

Using this tutorial you can decode any Ir remote Hex code.and we can apply it our project also like home automation,robot control etc.

You need-

Arduino Uno or any other arduino board

TSOP 1738 or 1838

small bread board

jumper wire

& for test a LED

At first you have to add a library ( Download from here)

after download unzip it & paste folder to arduino library folder

connect IR sensor to arduino like above  Schematic

Now upload first code to arduino

First code--

#include <IRremote.h>

int IRpin = 8;
IRrecv irrecv(IRpin);
decode_results results;

void setup()
  irrecv.enableIRIn(); // Start the receiver
void loop() 

  if (irrecv.decode(&results)) 
     Serial.println(results.value); // Print the Serial 'results.value'

     irrecv.resume();   // Receive the next value

After this press any key on remote ,Hex code will show on serial monitor

copy hex code of any key in your choice

Now upload sec…
