Components which we use in this project are listed below:

  1. Arduino UNO
  2. IC (TM 1637)
  3. 4 digit display
  4. Jumper wires

Construction of arduino UNO interfacing with traffic lights in proteus:

  • Connect the point 2 of arduino UNO to the pin 18 of IC
  • Connect the point 3 of arduino UNO to the pin 17 of IC
  • Connect the pin 1 of IC to GND
  • Connect the pin 2 of IC to the point A of 4 digit display
  • Connect the pin 3 of IC to the point B of 4 digit display
  • Connect the pin 4 of IC to the point C of 4 digit display
  • Connect the pin 5 of IC to the point D of 4 digit display
  • Connect the pin 6 of IC to the point E of 4 digit display
  • Connect the pin 7 of IC to the point F of 4 digit display
  • Connect the pin 8 of IC to the point G of 4 digit display
  • Connect the pin 9 of IC to the point DP of 4 digit display
  • Connect the pin 16 of IC to the +ve
  • Connect the pin 12 of IC to the point 4 of 4 digit display
  • Connect the pin 13 of IC to the point 3 of 4 digit display
  • Connect the pin 14 of IC to the point 2 of 4 digit display
  • Connect the pin 15 of IC to the point 1 of 4 digit display

Working of Arduino UNO interfacing with 4 digit display in proteus

Interfacing a 4-digit 7-segment display with an arduino UNO involves using the pins of arduino to control the individuals segments of the display to show different numbers of characters.

Applications of Arduino UNO interfacing with 4-digit 7-segments display in proteus are listed below:

  1. Countdown timer
  2. Temperature display
  3. Simple calculator
  4. Scoreboard
  5. Alarm clock
  6. Digital clock

Advantages of Arduino UNO interfacing with 4-digit 7-segments display in proteus are listed below:

  1. Simple display output
  2. Easy to use
  3. Cost-effective
  4. Customization
  5. Educational tool
