Hello,
I am currently working on a masters project where I am using an inflatable material that will inflate more rapidly when no one is detected and then once someone in detected the inflation will return to a more calm state (similar to that of a calming heartrate) I am using mini air pumps and an IR sensor to control this. I borrowed a code and set up the breadboard, but having trouble getting the air pumps to turn on. I will post the code and the circuit below. In the circuit diagram it shows A10 but however in my breadboard setup I used A5 as reflected in the code. Does anyone know why the air pumps are not bring activated?
