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

Image
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 battery 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() {   Serial.begin(9600);   irrecv.enableIRIn(); // Start the receiver }   void loop()  {      if (irrecv.decode(&results))      {      Serial.println(results.value); // Print the Serial 'results.value'       delay(10);      irrecv.resume();   // Receive the next value     } }     After this press any key on remote ,Hex code
