Cornel M Amariei

Cornel Amariei is a Romanian inventor and entrepreneur in the fields of Robotics and 3D printing. He has been working with the Arduino platform since its early days in 2007. His past experience involves large cargo gamma ray scanning robotics, ATM security systems, and blind assisting devices. In his spare time, he is a performing musician playing multiple instruments—predominately the guitar. He is also a swimmer, water polo player, and photographer. Over the years, he has built hundreds of Arduino projects, ranging from flying Quadcopters to levitating magnets and underwater robots. Currently, he splits his time between doing his undergraduate studies in electric engineering and computer science at Jacobs University in Bremen, Germany, and his start-ups and research and development job.

Temperature sensor

Almost all sensors use the same analog interface. Here, we explore a very useful and fun sensor that uses the same. Temperature sensors are useful for obtaining data from the environment. They come in a variety of shapes, sizes, and specifications. We can mount one at the end of a robotic hand and measure the temperature in dangerous liquids. Or we can just build a thermometer.

Here, we will build a small thermometer using the classic LM35 and a bunch of LEDs.

Getting ready

The following are the ingredients required for this recipe:

  • An Arduino board connected to a computer via USB

  • A LM35 temperature sensor

  • A breadboard and jumper wires

  • A bunch of LEDs, different colors for a better effect

  • Some resistors between 220–1,000 ohm

How to do it…

The following are the steps to connect a button without a resistor:

  1. Connect the LEDs next to each other on the breadboard.

  2. Connect all LED negative terminals—the cathodes—together and then connect them to the Arduino GND.

  3. Connect a resistor to each...
