Output Devices¶
Goals¶
Group assignment:
- Measure the power consumption of an output device.
- Document your work on the group work page and reflect on your individual page what you learned.
Individual assignment:
- Add an output device to a microcontroller board you’ve designed and program it to do something.
Prior Knowledge¶
In my final project of Electrical Engineering, I programmed a self-balancing robot. This involved using a motor driver.

Planning¶
I originally planned on churning the water with a spinning stepper. Revisiting this, I realized the obvious issue. Although it would look realistic, the board would likely mix with water regardless of the CAD around it.
New plan! I still enjoy those, so I could just create the same mechanism with a mini-golf style windmill. I would use a stepper motor, since I do not need precise control.
To consolidate the circuit, I will be using an L293D motor driver. The stepper does not require an encoder, I will only be controlling speed and direction.

Group Assignment¶
I was in a group with Kathryn Wu and Amalia Bordoloi.
