You should use a mechanism called persistance of vision for interfacing multiple seven segment displays. here is tutorial for mulplexing displays using 8051 microcontroller. http://www.shree-electronics.com/interfacing_multiple_7_segment_displays.htm
A seven segment display is a device used to display numbers and letters on things such as alarm clocks. A 7 segment display is simply seven LED's packaged in a pattern that allows numbers and letters to be displayed by illuminating different sets of LED's.
We cannot connect the 74ls138 straight with a seven segment display; for that we need a 7447(7 segment driver).
A: NO it is a display of seven segment to display a decimal of '0' to '9' it may have 8 LED for the point
A 7 segment display is an I/O device, and it is not necessarily used in microprocessors. The choice of I/O devices is a function of system design, not microprocessor design.
To connect a common anode 7-segment display, you would typically connect the common anode pin to a positive voltage source and the individual segment pins to current-limiting resistors connected to the microcontroller output pins. When you provide a LOW signal to a segment pin, it will turn on that segment.

A Loss of power or the blanking signal is on to begin with.
To create a 7-segment display in Visual Basic, you can use a combination of labels or picture boxes to represent each segment of the display. You need to define the segments (A to G) and control their visibility based on the number you want to display. For example, to show the number "3," you would set the relevant segments to visible. You can achieve this by using an array or individual controls, and updating their properties based on the input value.
