Temperature Measuring Device

OLED and Digital Temperature Sensor(DS18B20) With Arduino.
In the previous section, we interfaced OLED with Arduino and Digital Temperature Sensor (DS18B20) with Arduino separately. Now we are going to merge them together to make a temperature measuring device powered by a standard 5 Volt power supply or a power bank.


Items required:

• Arduino Nano
• OLED Display
• Digital Temperature Sensor (DS18B20)
• Vero Board
• Female Header
• Terminal Block
• 4.7k Resistance
• Jumper Wire
