Hi, I am a Design engineer in India graduated from IITM and currently working in start-up based in Bangalore. My specialization are in designing and bring different engineering verticals and making useful products.
For the same, I have been working extensively on Arduino UNO both in my college and at work. Also, I have worked on a customized controller with Atmega and ARM processor. So I believe I have came across enough troubles on Arduino and since have re-solved them using the skill sets I have acquired. I believe my comments will contribute to your community.
