This is a basic, 4-digit 7-segment display – red in color. It has a common anode. The display features one decimal point per digit, and individually controllable apostrophe and colon points. The LEDs have a forward voltage of 3VDC and a max forward current of 20mA. This is the way the display works. It’s multiplexed, so you select the digit by setting its pin (we’ll get into pins later) HIGH, and you select the segment by setting its pin LOW. You display multiple digits at once by rapidly cycling through them. Uses Timer, Counter, Watch, Stopwatch, Token Display machine and endless applications that you can think.
The Seven segment displays are used in today’s consumer devices like microwave ovens, washing machines, and air conditioners. They are a simple but effective way to display numerical data like time or quantity. Since they are made out of LEDs, they are a low-cost option for displaying information. They are widely appreciated for their features like accuracy, clarity, and optimum functionality.
