Reset the ATmega8U2 / ATmega16U2 of your dead Arduino Mega / UNO

Arduino not detected..??

Your Arduino was working fine until one day you connect it to the PC and find that the PC does not detect the Arduino.
You think there is either a USB cable issue or USB post issue, but none solve the problem.

Now you might be thinking that its the ATmega328 on UNO or  the ATmega2560 on the Mega is the culprit.
You try to reload the botloader on it and still the problem persist with “unknown driver present” or “problems with the current device”.

But the real problem is with the ATmega8U / ATmega16U on the arduino board used as a USB to serial converter, which does not let you connect the Arduino to the Computer.

Getting rid of the issue

Now you might panic that how are you gonna fix that SMD ATmega..:(
But the soluion is pretty easy and is just like a child’s play.

The Coastal Saga

As a kid, I watched in awe, how my dad rode his Yezdi… the two-tyred vehicle seemed way bigger and louder than other, similar vehicles which my uncles rode… My dad told me stories, of how he wished to tour around the world on his motorcycle and see each and every corner of the earth… I was just 3 yrs old when Dad left us… his dream unfulfilled. Well, I am living his dream now, mine as well.

I strongly believe that life is a continuous journey and not any particular destination, and with this belief I started traveling in and around West Bengal on my Royal Enfield Classic 350. Ahh…You might think why a motorcycle ? why by road ? Flying down or traveling by train would make the journey more luxurious.. Right..?
But for me traveling is not only to visit a point of interest and get back home. Traveling for me is all about exploring the unexplored, knowing the unknown, meeting wonderful souls from different culture, taste different food and share experiences.

My trips started to grow with confidence, from a day to few days.. from few days to a week and to few weeks. Meanwhile I was planning for a bigger trip, a trip of a lifetime… That is when the idea of ‘The Coastal Saga’ was born… This time was special as I wanted my wife to join me in this 10,600 kms ride ( including city rides ), across Southern and Central India. We planned to cover West Bengal, Odisha, Andhra Pradesh, Telengana, Tamil Nadu, Pondicherry, Kerala, Karnataka, Goa, Maharashtra, Madhya Pradesh, Uttar Pradesh, Bihar, and Jharkhand, and so we did… (more…)
