Interactive Device DesignCornell Certificate Program

Interactive products and IoT prototypes are no longer “nice to have.” Teams increasingly expect you to move from an idea to a working proof of concept that senses input, computes a response, and produces a meaningful output in the physical world. Cornell’s Interactive Device Design Certificate is built for that moment, with guided builds that help you translate technical concepts into functioning devices.

In this certificate program, authored by faculty from Cornell Tech, you will practice the full stack of interactive device creation: assembling and debugging circuits, programming microcontrollers, integrating sensors and displays, adding actuation and power planning, and then expanding into Raspberry Pi workflows, networking, and internet-connected interactions. You’ll also gain experience using open-source libraries so you can prototype faster and adapt existing code responsibly.

Just as important, you will learn with support. eCornell’s model combines faculty-authored content with expert facilitation, interactive discussions, and feedback on your project work so you can make steady progress even when hardware or code does not behave as expected.

If you want hands-on device-building skill, confidence troubleshooting real hardware and software, and the ability to prototype connected interactive experiences, you should choose Cornell's Interactive Device Design Certificate.

Most online learning for electronics and IoT falls into two extremes: highly theoretical content with little building, or self-directed tutorials where you are on your own when something goes wrong. Cornell’s Interactive Device Design Certificate is structured to help you actually get prototypes working, then understand why they work.

You learn in a small cohort with an expert facilitator who guides discussions and provides feedback on graded, multi-part projects. That matters in device design because progress often depends on systematic troubleshooting across wiring, power, sensors, and code. The program also keeps the work practical by pairing instruction with hands-on activities such as soldering, reading schematics, using debugging tools like Serial Monitor and Serial Plotter, integrating I2C sensors and an OLED display, controlling motors with appropriate power, and building connected interactions over the internet.

The Interactive Device Design Certificate curriculum is authored by Cornell faculty, and the learning experience emphasizes application: You adapt open-source libraries, integrate real components, and design increasingly complex behaviors (including state-diagram driven interaction) rather than stopping at isolated “hello world” examples.

Enrolling in Cornell’s Interactive Device Design Certificate also provides you with a 6-month All-Access Pass to eCornell's live online AI Workshops, interactive sessions led by world-class Cornell faculty that combine Ivy League insight with practical applications for busy professionals. Each 3-hour Workshop features structured instruction, guided practice, and real tools to build competitive AI capabilities, plus the opportunity to connect with a global cohort of growth-oriented peers. While AI Workshops are not required, they enhance certificate programs through:

• Integrating AI perspectives across most curricula
• Responding to emerging AI developments and trends
• Offering direct engagement with Cornell faculty at the forefront of AI research

Project work in Cornell’s Interactive Device Design Certificate is build-centered and cumulative, so you repeatedly design, assemble, program, test, and debug real interactive systems. You will complete multi-part projects such as:

• Preparing and assembling your electronics platform, then building and debugging basic circuits and programming a microcontroller to read a button and control an LED
• Integrating external components by mapping sensor inputs to outputs such as RGB LEDs and speakers, using and adapting sample code and libraries
• Working with more complex sensing and output by using devices on a shared communication bus, capturing and storing data, and presenting readings on a graphical display
• Designing interactive behaviors using state diagrams and implementing state-based logic in code
• Creating motion through actuation, including using sensor data to control a servo and planning power requirements for real-world use
• Setting up a Raspberry Pi, connecting it to peripherals, exchanging data with a microcontroller, and building a two-board interactive device
• Building an internet-connected prototype that uses messaging to share sensor data and adding “smarts” like speech synthesis and computer vision

By the end of Cornell’s Interactive Device Design Certificate program, you will have practiced taking an interactive device from concept to a working prototype, including the messy but essential skill of finding what broke and fixing it.

Cornell’s Interactive Device Design Certificate helps you build credible, demonstrable prototyping capability across electronics, embedded programming, and connected interactive systems.

Cornell’s Interactive Device Design Certificate, which consists of 6 short courses, is designed to be completed in 3 months. Each course runs for 2 weeks, with a typical weekly time commitment of 3 to 5 hours.

Coursework is largely asynchronous, so you can watch lectures, complete readings, and work on builds on your own schedule, while still benefiting from deadlines that keep you moving forward and an expert facilitator who supports your progress.

Because this program requires a shipped electronics kit, plan ahead to avoid delays. Registering at least two weeks before your intended start date and providing a valid shipping address helps ensure you receive the kit in time. Certificate and course fees are refundable per policy, but the kit fee is not refundable once shipped.
