Project I - 13. Queue Machine (1 Counters) with 7 Segment Display Based on Arduino

Queue Machine (1 Counters) with 7 Segment Display

Queue machine 1 counter with seven segment with 3 digit display and sound queue output. The counter clerk presses the NEXT key to dial the queue number, simultaneously 7 segment will displays queue number and extra queue number sound.

There are 2 buttons, the first is the NEXT button that is the key to call the next queue number, while the 2nd key to repeat the call without adding the queue number. Seven segment displays queue sequence. Sound is generated from IC ISD17xx, voice queue number recorded on the IC then Arduino access address of voice number using SPI communication.

Hardware Requirement

• Arduino Uno Board
• 3 Digit of 7-Segment with Common Anode
• Modul ISD 17xx (ISD 17180 is recomended)
• Speaker 0.5W 80 Ohm
• 2 Push Button
• Power supply +5 Volt
• Jumper

How it Works

1. Connect the Arduino with Peripherals needed.
2. Plug in the Power Source on the device.

3. Add some library if needed

4. Compile and upload the script program above to your arduino.
5. The first display on the seven segment

6. Press the Next button, so the queue number increases 1 and ISD issues a queue noise According to
    the one in the display

6. Press the Return button to redial the queue number without adding the queue sequence number.
