This is a digital temperature measurement device powered by the Arduino UNO R3. It is quite simple and a very handy thing to be able to make. A suitable project to learn about Liquid Crystal Displays (LCDs) interacting with an Arduino.

Step 1: Gather the Components Needed

For this project you will need:

- An Arduino with USB connectivity

- 220 ohm resistor

- 10K Potentiometer

- Arduino-compatible 16 x 2 LCD

- Temperature sensor

- Breadboard and wires

Step 2: Get Power

To give your breadboard power, connect the 5v and GND pins on your arduino to the + and - on the side of the breadboard respectively.

Step 3: Wire Up the Temperature Sensor

Connect the left pin on the flat side of the temperature sensor to +. The centre pin of the temperature sensor goes to A0 (Analog Input 0). And the right pin on the flat side of the temperature sensor goes to -. The temperature sensor is now active.

Step 4: Wire Up the LCD and Potentiometer

To make explaining a lot easier, use this diagram to wire up the LCD and potentiometer. The potentiometer will control the brightness/contrast of the LCD.

Step 5: Program

This is the code I wrote. Feel free to copy.

Step 6: End Result

<p>Млять, well who so makes out projects?<br>Neither temperature sensor models, nor scheme, nor opportunity to copy a code. <br>Kick...</p>
<p>pleas epost copy of code in comment box.</p>
<p>Why would you need the 220 Ohm Resistors? The LCD can take all 5V and so can everything else on the board, comparing to the one I built, and secoundly the Temp Sensor, was it the LM36GZ</p>
<p>maybe it would be good to write what sensor is used....</p>
Nice Ible ...
