That’s right Jeff Brown from RHIT has told me this morning that he has finished anchoring our circuit bored together for the P.A.I. This image here is just a random circuit, but it is similar to the P.A.I.'s. The function of our interface is to route electrical current based on time. The electrical current is routed through switches and this allows our program to open and close valves according to time which in turn release smells. Now programming and testing can start. My thanks go out to my partner in science Jeff Brown.
