#SERIAL 7 SEGMENT DISPLAY ARDUINO HOW TO#

There is also an extra eighth LED on a seven-segment display which is used to display dots. If this pattern is controlled in a specific way by turning on and turning off LEDs, a seven-segment device will display a unique number. These light-emitting diodes are arranged and packed inside a single display with a specific pattern in mind. Let’s start the main part of this tutorial by answering a question: what is a seven-segment display? As its name suggests, a 7-segment device consists of 7 light emitting diodes. One of the popular examples for the use of a seven-segment display is the NASA space shuttle launch countdown display. The seven-segment display has many applications in embedded systems and Arduino based projects. If you notice the digital clock, it also uses 7-segment devices.įor example, if you are designing an ac voltmeter or ac current meter using Arduino, you can use a seven-segment display instead of a 16X2 liquid crystal display to display voltage and current values. In movies, you have seen a hero trying to deactivate a bomb and at the time he keeps his eye on the digital clock. For example, if you go to the market, you will see a large digital clock based on a seven-segment display. You will find many practical applications of these displays around you. Seven-segments are practical, efficient, and cost-effective devices that are used to display alphanumeric numbers.
