I design and build embedded hardware — Arduino and ESP32 firmware, sensor interfacing, motor control and the small, unglamorous power problems that decide whether a prototype survives its first week. Electronixity grew out of that work: sourcing decent components in India was harder than building with them, so we started stocking the parts we actually use. Everything published here gets built before it gets written. If a tutorial says a sensor is active-LOW, it's because that's what the module on my bench did, and the bill of materials links to the exact part I used rather than a generic category page. Where a build has a failure mode, it's documented in the troubleshooting section instead of being quietly left out. I also take on student and academic projects through Electronixity's project service, which is where a lot of the troubleshooting content on this site comes from — the same handful of mistakes turn up every semester.
