At this stage of the project, development has moved into the verification and validation phase. I developed an iOS application using Shifted that communicates via Bluetooth with a Raspberry Pi, which is connected to a motor step driver controlling a motor. This subsystem allows wireless control of the motor through the mobile app.
For verification, I focused on testing the functionality and reliability of my subsystem. I tested Bluetooth connectivity to ensure stable pairing and consistent communication between the app and Raspberry Pi. I also verified that commands sent from the app (such as start, stop, and speed changes) were accurately received and executed by the motor system. Motor behavior was observed and compared to expected outputs to confirm correct operation. Additionally, I tested the user interface to ensure all controls function properly and respond as intended.
For validation, I evaluated the complete system to ensure it meets the overall project requirements. This included end-to-end testing from user input on the app to motor movement. I measured response time and checked system reliability during continuous use. I also tested the system in realistic scenarios to confirm that it meets the intended use case of simple and effective remote motor control.
To analyze results, I compared measured performance (such as response time and accuracy) against the design requirements. I also conducted repeated tests to ensure consistent performance and monitored for errors such as missed commands or delays. Overall, the system is functioning as expected, and continued testing will focus on improving stability and performance under more demanding conditions.
