A single IC will only able to operate the single display. The input on the IC will be in binary form and output will also in binary form too. The use of IC will also be by the resistors because the most operating voltage uses with CMOS/TTL devices are 5 volts. Therefore, The IC will always depend on which type of display we are using. Multiple ICs are useable with the display to operate with only a small number of pins. It also uses the resistor for power protection. The LED’s power limit is according to the other simple LED lights. The light from one led won’t affect the other and gives a clear and clean output. The specific dark color case is used to limit the LED light to itself. Whenever any pin gets the power input of specific voltages then it starts glowing. Then all the other pins come out of the package as a single pin for each LED. That pin decides when the anode is common or cathode. In the device, all the LEDs are placed at a 90-angle from minium two LEDs. In the 7-segment display, the simple LEDs uses to display the decimal character. Power input on pin10 lights up the middle led. Pin8 is a second common ground pin, works like same as pin3. ![]() ![]() The top led of the 7-segments is at pin7. There is a decimal point on the 7-segment which uses the pin5 to light up. Pin4 light up the bottom right led to the display It depends on the type of the 7-segment either it is the common cathode or anode. Pin2 helps to light up the bottom-most led. The first pin1 connects with the left bottom LED of the display.
