An Ardiuno-based Responsive Car
for Engineering Outreach
Purpose
Breaking away from the conventional "mouse-trap cars" of previous years at Connections Engineering Outreach, I took the initiative to analyze participant feedback trends from past surveys. Recognizing a clear desire for more technically advanced projects, I spearheaded the creation of an Arduino-based gesture-controlled car. The end goal was to allow users to intuitively control the car's movement by tilting the controller in their desired direction of travel.
The scope of this project included analyzing data, creating a functional prototype, sourcing components, documenting the process, debugging, rigorous testing, and teaching the material to participants.
Process
The component selection prioritized cost-effectiveness and reliability, crucial for teaching participants with varying levels of experience. Focusing on achieving flawless performance and repeatability, I ensured the code and components worked reliably each time. This approach, considering budget constraints and the need for functionality, guaranteed project success.
The Arduino Uno served as the central controller for its affordability and compatibility with other components. An MPU 6050 accelerometer enabled gesture control, while an H-bridge motor driver (L298N) powered the four DC motor wheels.
Despite the initial plan for a wireless setup, practical considerations and a crowded environment led to a wired configuration. This decision not only resolved potential interference issues but also contributed to the project's overall cost-effectiveness.

Impact
The gesture-controlled car project is a favorite within the enrichment program, earning the highest overall rating among 20+ summer projects. Its impact was further solidified by an outstanding 95% customer satisfaction rate, indicating its effectiveness in meeting and exceeding client expectations.
This project's success can be attributed to its emphasis on innovation and active participant engagement. It not only demonstrated the potential of integrating more advanced content into education but also underscored the importance of adapting projects to align with the evolving preferences of clients.
The overwhelmingly positive reception of the project has led to the expansion of the mechatronics program at Connections.
