Inside the 100 Days IoT Challenge: The Student Who Refused to Slow Down at Day 75

It is truly inspiring to witness the discipline, curiosity, and commitment Kritish Mohapatra demonstrates in his “100 Days 100 IoT Projects” journey.

Reaching Day 75 is not just a numerical milestone. It reflects consistency in action, clarity in purpose, and a deep passion for building rather than merely consuming knowledge. Undertaking a challenge of this scale, while documenting and sharing it openly for the benefit of others, speaks volumes about his mindset as a future engineer and contributor to the IoT ecosystem.

What stands out most is not only the quantity of projects, but the diversity and practical relevance of what has been built. From ESP-NOW peer-to-peer communication systems that eliminate dependency on traditional WiFi infrastructure, to the development of “micropidash,” a lightweight IoT dashboard library that runs directly on microcontrollers, these are not academic exercises. These are real, usable solutions that address the constraints developers face in the field.

His work on an AI-powered GPIO controller further demonstrates his ability to bridge hardware with intelligent interfaces, moving beyond basic automation into more intuitive human-machine interaction. This reflects a strong understanding of where IoT is heading: systems that are not only connected but also responsive and context-aware.

Equally impressive is the Wi-Fi-controlled 4WD robot car and the smart indoor security system integrated with cloud logging and email alerts. These projects highlight an important principle that many overlook. IoT is not about individual components. It is about orchestrating sensors, connectivity, platforms, and user interfaces into a complete working system that delivers value.

Kritish’s use of the FAVORIOT platform for real-time logging and alerting is a strong example of how students can move beyond isolated prototypes into connected, cloud-enabled solutions. It shows an appreciation for end-to-end system thinking, from device to dashboard to actionable response.

Beyond the technical achievements, something equally important is happening here. The decision to make all projects open source and accessible for students reflects a mindset of contribution. It shifts the effort from personal achievement to community impact. This is how ecosystems grow, not through isolated brilliance, but through shared progress.

Recognition from respected communities such as the MicroPython ecosystem and the Python Software Foundation, as well as features in industry newsletters, further validate the quality and relevance of his work. It is encouraging to see emerging talent not only building consistently but also gaining visibility on a broader stage.

Maintaining this level of momentum over 75 consecutive days requires more than skill. It requires resilience. There are always days when motivation dips, when projects become more complex than expected, or when results do not immediately match expectations. Continuing despite that is what separates casual learners from serious builders.

This journey also sends a strong message to other students and young engineers. Mastery is not built through occasional effort. It is built through daily practice, iteration, and the willingness to learn in public.

As Kritish moves into the final stretch of his challenge, the foundation he has built will continue to compound. The remaining 25 projects are not just about meeting a target but about deepening understanding, improving systems thinking, and strengthening his ability to translate ideas into working solutions.

This is the kind of effort that shapes not only a strong portfolio but also a strong mindset.

Congratulations to Kritish Mohapatra on this remarkable milestone. The consistency, openness, and technical depth demonstrated in this journey set a strong example for the next generation of IoT builders. The path ahead looks promising, and the impact of this work will likely extend far beyond this 100-day challenge.
