| Dec 16, 2017 at 20:27 | comment | added | Mikael Patel | Check pin modes. Should be INPUT_PULLUP and OUTPUT. Also consider debouncing. | |
| Dec 16, 2017 at 20:15 | comment | added | Chandramauli Chakraborty | @per1234, Any solution? | |

| Dec 16, 2017 at 19:45 | comment | added | per1234 | Add in the Serial test line to your code and note that part is printed so that people know your Serial communications is working correctly. You could add a comment to that line to remind yourself that it's only there for debugging and can be removed later to save memory. Your question should stand by itself without needing to read the information in the comment thread. | |

To verify serial communication is working, add this line after your Serial.begin() statement: Serial.println("Program starting");. Let us know whether you see that line printed when you open the Serial Monitor.

| Dec 16, 2017 at 19:30 | comment | added | Chandramauli Chakraborty | In my opinion, it may be some syntactical error. | |

| Dec 16, 2017 at 19:29 | comment | added | Chandramauli Chakraborty | The serial monitor should provide the key pressed on it. | |

| Dec 16, 2017 at 19:27 | comment | added | user31481 | Not working doesn't give us any information. What is not working? How is not working? Is it hardware or software? What is the right result in your opinion? | |
