Agam Robotics is a startup based in Bangalore that builds drone components, including flight controllers, GNSS modules, optical flow sensors, rangefinders, power distribution boards, and power modules. The company's stated focus is on building products from the bottom up within India, with PCB fabrication, assembly, enclosures, plastics, and aluminium heat-sink components all done in India.…
If you are working on IoT projects, you already know the importance of an M2M IoT SIM card for remote monitoring and tracking. For those who are new and wondering why you need a special M2M SIM card when you can just use your normal SIM card, here are two strong reasons to consider one.
Cost: If you are running a…
In this tutorial, we are going to see how you can create a custom Graphical User Interface(GUI) using LVGL and our favourite Arduino IDE. You can use any kind of microcontroller for this project; the only thing you need to do is to include the right pins in the Arduino code. Here, I’m using an ESP32-C3 based smartwatch for the demonstration. This has a display, touch, controller and…
At Electronica 2026, while exploring the Silicon Labs booth, I came across a wireless networking technology that was surprisingly new to me, Wi-SUN. As embedded engineers, most of us are already familiar with technologies like BLE, Zigbee, Matter, Thread, and LoRa when it comes to IoT connectivity. But Wi-SUN felt different from the moment I saw the live demo running at the booth.
After…
It’s something we’ve been hearing for years, India building its own microcontroller. But most of the time, those conversations stayed within labs, government schemes, or early prototypes. What’s been missing is a product that actually makes its way into the hands of developers and into real-world applications.

At a recent community webinar focused on building robotics companies in India, Raghvendra Sutar, founder of Kikobot, discussed how he started the company, the products it has developed, the challenges of manufacturing robotics hardware, and the company’s plans to expand into industrial robotics.
We host monthly live sessions with engineers, developers, builders, and guest speakers from…
Adviteey Mehaindroo, the founder and CEO of Zinikus, credits CircuitDigest as one of his earliest learning grounds. Now he's sitting down with the same platform, talking about running a robotics company with a half-million-dollar valuation. He describes Zinikus as “a robotics company focused mainly on humanoids, but also catering to the advertising and hospitality sectors with robotics.”

As I sit down to write this piece, I notice the fan whirring above and, for the first time, it occurs to me that it runs on an induction motor. So does every other fan in my office and my home. These motors have been around for a long time, not because they’re the best options out there, but because they’re cheap and do the job. BLDC motors have gained a bit of popularity, but are pricier and…
From blinking LEDs to building robots, the Arduino UNO was the development board that made electronics feel possible for students, professionals and a lot of hobby makers around the world. While keeping the familiar idea of Arduino UNO and its form factor the same, they have launched this board called the Arduino UNO Q, which is a more capable variant of the original…
Model Name: FNIRSI-1014DAbstract :An oscilloscope that retails at INR 13K basically covers all of the hands-on subjects a 4-year engineering syllabus teaches in theory. The only issue is that none of this is practiced. We barely get past MCUs hands-on.This…
Bluetooth communication is everywhere. Due to its low power consumption, we can see it in a lot of our day-to-day gadgets. Behind the scenes, it's all about signals. Let’s explore what really happens when data is transmitted or disturbed via Bluetooth. This project is based on an ESP32 and two NRF24L01 modules, and we are going to learn how we can generate a 2.4 GHz…
