【 摘 要 】

Project-based learning (PjBL) is an activity, which can be done individually or in groups, that goes on over a period of time and its objective can be a product, presentation, or performance. It can make students develop their skills and become more engaged in learning because they can solve problems that are met in real life through a project. The project was a weight meter using a d.c. deflection-type bridge circuit and a VU meter, which was realized by a group of three students (the first three authors). We were of the 2ndyear of undergraduate physics program that are taking the Measurement and Data Processing Techniques course in the period of January to April 2015. We worked together with our lecturer and tutor as our advisers. In making the weight meter, we have done the following roles in PjBL: 1. Planning the project and setting a timeline, 2. Doing research, 3. Creating first draft, 4. Rewriting the project report, and 5. Submitting the project. Under the guidance of timeline, the project has been completed timely. A force sensing resistor (FSR) sensor was employed to convert a body mass to resistance of the bridge circuit and the VU meter was modified to be a display of the weight meter. The weight meter could be used to measure a body mass up to 5 kg.
