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.

The 7-segment display

Since the beginning of electronics, 7-segment displays have been used to display numbers. They are easy to connect and understand, and quite fun to use once they are properly implemented. We can use such a display to show the status of our system or to show data from a sensor.

Getting ready

The following ingredients are needed for this recipe:

  • An Arduino board connected to the computer via USB

  • A breadboard and jumper wires

  • A 7-segment display

  • Resistors between 220–1,000 ohm

How to do it…

Follow these steps in order to connect a 7-segment display to the Arduino:

  1. Mount the 7-segment display on the breadboard.

  2. If the display is a common anode (+) configuration, connect the common anode (+) pin to the VCC port on the Arduino. If it is a common cathode (-), connect the cathode to the GND port on the Arduino.

  3. Connect each individual segment pin to one individual Arduino digital pin using a resistor.

Schematic

Here is one possible implementation of a common anode (+) 7-segment display...
