Assessment#
from Assessment - Input Devices
-
Group assignment
- Probe an input device(s)’s analog and digital signals
- Document your work to the group work page and reflect on your individual page what you learned
-
Individual assignment:
- Measure something: add a sensor to a microcontroller board that you have designed and read it.
-
Learning outcomes
- Demonstrate workflows used in sensing something with input device(s) and MCU board
-
Have you answered these questions?
- Linked to the group assignment page
- Documented what you learned from interfacing an input device(s) to microcontroller and how the physical property relates to the measured results
- Documented your design and fabrication process or linked to previous examples.
- Explained the programming process/es you used
- Explained problems and how you fixed them
- Included original design files and source code
- Included a ‘hero shot/video’ of your board
- FAQ
- What does “probe” mean?
Answer: A test probe is a physical device used to connect electronic test equipment to a device under test (DUT). To probe means to measure, observe or monitor signals with test probes. - Is the satsha kit/fabduino I fabricated considered a valid board for this assignment?
Answer: Fabricating an unmodified board is considered as electronics production. It doesn’t count towards any design skill. You must make some significant changes to the original satsha kit/fabduino, for the board to be considered your own design. - Can I use a breadboard and/or jump wires to interface my input device(s)
Answer: No. You can’t use a breadboard. If you use wires, they must be soldered or connected with connectors.
