Tanmoy Kundu

I'm the founder of Circuit Diagrams, holds a B.Sc in Electronics and a Master's in Computer Applications (MCA). With a strong foundation in both hardware and software, I combines my passion for electronics and programming to create practical, real-world DIY projects. Driven by the goal of simplifying embedded systems and IoT development, I designs, tests, and documents each project to ensure it's accessible for students, beginners, and makers of all levels. My mission is to turn complex concepts into easy-to-follow solutions through detailed tutorials, eBooks, and custom circuit designs.
