Hi guys, i'm new with the Arduino program and now i'm working on my senior project. To be honest i don't know how to combine between the sensors that i used. Therefore, i searched and i found out i must add each setup together and after it did it it tells me that the interrupt setup is not declared. For now, i'm asking for combining the gas sensor (MQ-9) and the pulse sensor and here are the codes. I wish you guys help me in combining between them.
I attached for you the pulse sensor codes and it interrupt and the gas sensor codes.
