I have tried a lot to program my project but I have failed and problems often appear in the code
I try to program a project that measures a person’s heartbeat by using a pulse sensor and connecting it to arduino uno and using the “if” function. If the heartbeat is greater than 240 or less than 180, the buzzer works and sends a notification to the phone and displays the number of heart beat on 7 segment
