Arduino Uno has always helped to build projects easily and make them look more attractive. In this project, we are going to make an Arduino Uno calculator which will take the values from user by using the 4X4 keypad and then will perform the calculations to get the result. After calculating the result, it will print those calculated values on Nokia 5110 LCD. This Arduino Uno based calculator can perform four operations which are addition, subtraction, multiplication and division.

Digital Thermometer using Arduino and DS18B20 Sensor

In this project, we are going to make a Digital Thermometer using Arduino Uno. We will use DS18B20 temperature sensor to sense the temperature and Nokia 5110 LCD to display it. DS18B20 is a 1-Wire digital temperature sensor manufactured by Maxim Integrated and is capable of reporting degree celsius with 9 ~ 12 bit precision.
