Week 04: Embedded Programming

FabDino Game on QPAD

Hero image FabDino I constructed QPAD and created the Dinosaur game you see on Chrome browser.


Assignments

Group assignment:

  • Demonstrate and compare the toolchains and development workflows for available embedded architectures
  • Document your work to the group work page and reflect on your individual page what you learned

Individual assignments

  • Browse through the datasheet for a microcontroller
  • Write and test a program for an embedded system using a microcontroller to interact (with local input &/or output devices) and communicate (with remote wired or wireless connections)

1. Group Assignment

We compared several toolchains and development workflows in group assignment and documented on [FabLab Kannai group work page] (https://fabacademy.org/2026/labs/kannai/Weekly_Group_Assignment/week04/).

I learned historicadl method using “Programmer” and some other methods and learned that writing embedded program to a board was a lot of fuss in the past and it is getting easier and easier.

2. Brouse through the datasheet for a microcontroller

I am very interested in the Seeed xiao family of boards, and wanted to find out which board is suitable to drive motors and handle camera information. I used Google NotebookLM to ask questions about the data sheets. It seems Seeed Studio XIAO ESP32S3 Sense is the best choice as it natively supports OV2640 or OV3660 camera sensors and has high processing power.

Seeed Studio XIAO ESP32S3 Sense

3. Developing “FabDINO” game on QPAD

FabLab Kannai Instructor Tamiya-san kindly shared with me the “QPAD” board from the instructor workshop in Norway. I soldered necessary parts and then developed a Dinosaur game in MicroPython and Thonny.
