LCD temp display with smoothing

This is my first real project. Its a 16X2 lcd that displays the temperature in F and C. I used the TMP36 sensor and code from the Vilros Ultimate Starter kit and added code from the LCD tutorial. Just for fun I added the smoothing code from Simon Monk’s “Programming Arduino Next Steps” in chapter 13. Took about 5 hrs total but it was time well spent. I will try to add the code and a picture.

//The circuit:
//* LCD RS pin to digital pin 12
//* LCD Enable pin to digital pin 11
//* LCD D4 pin to digital pin 5
//* LCD D5 pin to digital pin 4
//* LCD D6 pin to digital pin 3
//* LCD D7 pin to digital pin 2
//* LCD R/W pin to ground
//* 10K resistor:
//* ends to +5V and ground
//* wiper to LCD VO pin (pin 3)

//Thanks to Simon Monk, read both beginner books several times to get this far.
// And Vilros Ultimate Starter Kit, money well spent.

#include <LiquidCrystal.h>// include the library code:

// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
const int temperaturePin = 0;
const float alpha = 0.99;
float smoothedValue = .72;//number selected to bias temp to avg room temp

void setup() {

  lcd.begin(16, 2);  // set up the LCD's number of columns and rows: 


void loop() {
  float degreesC, degreesF;  

  float newReading = analogRead(temperaturePin) *(0.004882814);
  smoothedValue = (alpha * smoothedValue) + ((1 - alpha) * newReading);
  degreesC = (smoothedValue - 0.5) * 100.0;
  degreesF = degreesC * (9.0/5.0) + 32.0;
  lcd.print("Current Temp:");// Print the top line title
  lcd.setCursor(0, 1);
  lcd.print("F ");
  lcd.print (" C ");



Take care all.
