This project is change from “Arduino Thermometer + LCD I2C-By JureINV” Here is the link:<https://www.instructables.com/id/Arduino-Thermomet...>.

I change the way it print the word and the Celsius into Fahrenheit. If you are not feeling well and you want to check your body temperature. It is a good helper for you!

Supplies

An Arduino ( I used Leonardo, UNO and NANO is find to use too.)

Some Bread board wires

A 10K resistor

A LCD+I2C

Step 1: Connecting the Components

On the pictures above, you can see how you should connect the components on the board. Solder the two pieces together as shown on the pictures above.

If you are using Uno/Nano, the SDA and SCL pins are A4 and A5 respectively. Connect the pins on the LCD I2C module to the ones on the Arduino.

Step 2: LCD and I2C

I2C module is a impressive helper for LCD. You don’t need to set so mach pins to let it show simple words. Just 4 pins in I2C that you need to connect.
If you are using Uno/Nano, the SDA and SCL pins are A4 and A5 respectively. Connect the pins on the LCD I2C module to the ones on the Arduino.

There is the test code.
Test code

Step 3: The Code

Normal person’s temperature should be in a range of 95~104 F. It is not so good about measure room’s temperatures.

Step 4: Finished!

Congratulations! The work is done. After you upload your code to Arduino board. You just need to input some Electric into it. You can measure your temperature anytime and anywhere.
