Introduction: Arduino Serial Command Recognizer

By

Generally we use arduino serial monitor to see our desired value driven by arduino.

We can use it as a command input as well. Here in this project i'll show you how it can be done.

Apparatus required:

  • 7 segment led
  • Arduino UNO
  • Jumper wire

Step 1: Connect the 7- Segment Display

  • Connect the seven segment display with following arduino board pins:
  • Connect "a" to digiatal pin 2 of your Arduino board.
  • Connect "b" to digiatal pin 3 of your Arduino board.
  • Connect "c" to digiatal pin 4 of your Arduino board.
  • Connect "d" to digiatal pin 5 of your Arduino board.
  • Connect "e" to digiatal pin 6 of your Arduino board.
  • Connect "f" to digiatal pin 7of your Arduino board.
  • Connect "g" to digiatal pin 8 of your Arduino board.
  • Connect "h" to digiatal pin 9 of your Arduino board.

Step 2: Upload the Code

Upload the code to your Arduino board using arduino IDE.

Step 3: Open Serial Monitor and Press Number

Now it is ready for serial communication.

Open the serial monitor from top-right corner of arduino IDE.

Press any number from your computer and same will be displayed on seven segment display.
