The project I made which I call it the Seventh glitch simply because from 7-9 the red LED is off to indicate that the limit is reached which is from 7-9.This Project was made by a student from the Tshwane University of technology which is in South Africa. I had limited resources which I got from school as I am Studying Electrical Engineering therefore, I combined the limited resources I had to make this project. We can apply this in Elevators, digital clocks, scoreboards, in electronics labs for testing binary inputs.

Supplies

Resistors
LEDs(Red,Orange,Green)
Breadboard
Multimeter
4-bit switch
Jumper wires
Seven Segment display
9V Battery
74ls47 IC

Step 1:

Open Proteus & simulate on proteus before building the circuit physically

Step 2:

Connect the circuit according to proteus
Gather all the required supplies such as Resistors, Leds(Red,Orange,Green),Breadboard,Multimeter,4-bit switch, Jumper wires, Seven Segment display,9V Battery,74ls47 IC
Connect the resistors to the positive terminal of the battery the to the switch
Ground the switches
Connect resistor 4 to pin 7 of the 74LS47 IC
Connect R3 to pin 1 of the IC
CONNECT R2 to pin 2 of the IC
Connect R1 to pin 6 of the IC
Connect the seven Segment to the 74LS47 IC & make sure to power the seven segment to VCC or positive terminal.
Pin 8 of the IC must be grounded with pin 18 connected to VCC which is the positive terminal of the battery
Red LED connected to pin 6 of the IC & ground
The Orange LED Connected to pin 6 and 2 of the IC with pin to anode and pin 6 to cathode
The green LED has cathode connected to pin 2 and anode connected to VCC
