Reflection:

Reflecting on the development journey of this smart switch, it has been quite a rollercoaster. From the outset, configuring the development environment proved challenging. Networking issues with the VMware virtual machine prevented Home Assistant from obtaining an IP address, highlighting the critical importance of establishing a solid foundational setup.

During the hardware debugging phase, the OLED screen's “distorted display” and “vertical stripes” became the most significant stumbling blocks. Progressing from initial I2C communication failures (NACK), through identifying signal interference caused by excessively long DuPont wires, to finally confirming the screen driver chip was the SH1106 rather than the common SSD1306, this journey provided profound insights into the critical roles of hardware anti-interference measures (such as frequency reduction to 10kHz) and underlying driver compatibility.

Additionally, addressing the unique mechanical structure of the seesaw switch, I repeatedly adjusted the servo's bidirectional swing logic and angles, ultimately achieving a seamless closed-loop between physical control and software logic. Though the journey was arduous, witnessing the screen clearly display real-time data and responding smoothly to Siri voice commands transformed all efforts into a profound understanding of the ‘hardware-software integration’ in IoT and an immense sense of accomplishment.

Games Development / Week 1 Homework

-
Image
  Week 1 Homework To do: Individually come out with a game idea (or many ideas, remember the limitations), and make your first game pitch. Some lucky (or unlucky) students will be selected to do a 10-minute presentation of their game idea(s) next week on September 30. No specific format for now (we’ll do Game Design Document in a later class), so try to find the most creative and effective way to convey your game ideas. This may not end up being your Final Project, but it will still contribute to your Continuous Assessment grade. Hence, document the process in your blog. Submit the link to your blog post by Sept 29 midnight.

Embedded System Project 1   Week 1  This week we've had a general introduction to the embedded system, and we've covered it in class. An Embedded System is a specialized computing system that is embedded into a larger device or system to perform specific tasks. Unlike general-purpose computers, embedded systems are highly optimized , have specific functions , and are not used for general computing . They typically consist of hardware (e.g., microcontrollers, sensors, memory) and software (e.g., firmware, real-time operating systems). Key Features of Embedded Systems： 1. Specific Functionality Typically performs only specific functions, such as control, monitoring, or data processing. 2. Limited Resources Limited in computing power, storage, and power consumption, requiring efficient optimization. 3. Real-time Performance Many embedded systems must respond within a specific time frame, such as in autonomous driving systems. 4. Low Power Consumption Many embedded devices (e.g...

 Assignment1 Trending Experience Todo: Task 1 helps you explore current Augmented Reality (AR) trends and understand marker-based , markerless , and location-based experiences before choosing your final project idea. Research AR Trends Experiment Reflect Propose 3 Ideas Processing: Research AR Trends I have identified three commonly used AR applications on the market to serve as my inspiration. 1. Apple Ar :   These applications combine the limitless choices of online shopping with the “hands-on experience” of offline retail, ultimately aiming to eliminate consumer uncertainty during purchases. By overlaying virtual product models onto real-world environments at a 1:1 scale, users can intuitively assess size, style, and outfit compatibility, enabling more informed purchasing decisions. User input:  Previewing an orange iPhone 17 Pro Max on my computer keyboard App output: 2. Particle Cam: The core value of this type of application lies not in “previewing products” or “...
