7-Segment Display

One of the oldest and primarily used methods for displaying decimal numbers in basic electronics devices is 7-Segment #Display. This device is an alternative for the dot #matrix displays which is considered more complex.7- Segment display device is a combination of #LEDs, in particular, 7 LEDs that together form the whole display. The device consists of pins connected to the controllers through the wires.


The article deals with the setting up of the circuit with a 7-Segment Display and interfacing it with Arduino to display the different digits one by one. It describes the working of the circuit along with the code explanation. The article also covers the working and configuration of the 7-Segment Display with Arduino in detail.





Hardware List


The following components are used for building the circuit.



Arduino
Arduino

Arduino board is a microcontroller that is used to accept inputs from sensors connected and provide an output action on the desired device connected to it. The sensor inputs can be that from light-detecting sensors, motion sensors (Ultrasonic or IR), temperature sensors, etc. The output function done on the devices can be turning on an LED, the sound of a buzzer, or a Serial monitor display.




Breadboard
Breadboard

The breadboard is the basic component of any circuit building process. All components, be it input sensors or output display devices are connected to the #Arduino or any other microcontroller using wired connections through a breadboard. The holes in the breadboard are in series. There are various sizes like full-sized, half-sized, and mini breadboards.
