Passionate about bridging the physical and digital worlds through embedded systems, IoT solutions, and electronics innovation. From sensor to cloud — I build it all.
I'm Anbumathi Chezhian, an Electronics & IoT Project Developer with a passion for creating smart, connected systems that solve real-world problems. My work lives at the intersection of hardware and software — where circuits meet code.
I design and build end-to-end IoT solutions: from schematic design and PCB layout, to embedded firmware, cloud integration, and data dashboards. Every project I take on starts with curiosity and ends with something that actually works.
When I'm not building prototypes or flashing microcontrollers, I'm exploring new sensors, protocols, and platforms to push what's possible in the connected ecosystem.
A custom 4-key productivity macro pad powered by the Seeed Studio XIAO RP2040 and KMK Firmware. Features dedicated shortcuts for KiCad, Spotify, and system tools with an idle RGB rainbow effect.
An electronics project exploring how chips like the 555 timer and 4017 counter interact to create sequential LED patterns. Built following the Hack Club guide with custom PCB design.
A high image quality camera system built on Raspberry Pi — capturing sharp, detailed images with custom configurations for embedded imaging applications.
A compact, portable Windows-based tablet built using a LattePanda single-board computer, a 7-inch IPS capacitive touch display, and a battery-powered setup — a fully custom handheld PC.
A custom development board engineered for modern computing and embedded innovation. Designed for flexibility, scalability, and reliability — built for students, makers, and developers to prototype freely.
Hack Clubis the world's largest nonprofit network of teenage makers & coders — with over 100,000 members across 1,000+ clubsin 30+ countries. Founded in 2014, it's a 501(c)(3) nonprofit where teens aged 13–18 build real projects, attend hackathons, receive hardware grants, and learn by shipping — not sitting through lectures. Members get access to a global Slack, free hardware grants, perks like GitHub Education, and fiscal sponsorship through HCB to run real-world events and clubs.
HCB is Hack Club's financial platform — giving teen-led teams real nonprofit infrastructure, a bank account, and debit cards to run events and projects. I earned approximately $100 in 2025 through project contributions and Hack Club programs.
Began exploring basic electronics — breadboard circuits, resistors, LEDs, and the fundamentals of electricity. Built first Arduino blink project.
Mastered Arduino programming, worked with motors, sensors, displays, and communication protocols like I2C and SPI.
Transitioned to ESP32/ESP8266, learned MQTT, connected devices to cloud platforms like Blynk and ThingSpeak. Earned NPTEL IoT certification.
Started building complete IoT systems end-to-end. Participated in hackathons, earned certifications, and began sharing projects publicly.
Exploring the convergence of AI with IoT — edge computing, TinyML, and building smarter, more autonomous connected systems.
Have a project idea, a collaboration in mind, or just want to talk electronics and IoT? I'm always open to connecting with fellow makers, developers, and innovators.
