In Applied Science and Engineering this term we have been focusing on the design process and creation of a device involving an ultrasonic sensor. We first learnt about the main steps of design: defining a problem, gathering information, generating alternatives, analysing and selecting the best alternative, designing and building the prototype, and testing and evaluating. With this knowledge, we were able to plan and begin designing our prototypes. A large majority chose to create sensors that would help people park their cars, but others chose more creative designs such as sensors that helped blind people complete certain tasks.

Throughout the term, we had to make a written report which outlined in more detail the design process and how it related to the problem we decided to solve. Then came building the prototype. We were able to use any material we wanted, but most chose cardboard or plastic as they were easy materials to find. We then had to code our MicroBit with the ultrasonic sensor code and build the circuit wiring that was necessary for the sensor to function. Some students added LED’s or speakers to help users when the sensor detected a certain distance. Finally, students tested and evaluated how their sensor worked to fix their problem. In total, this project offered students an insight into the process of design, allowed us to learn more about ultrasonic sensors and their potential uses throughout society.
