cehic1994's video: Arduino pro mini problem with code uploading viausb to ttl serial adapter

I have used Arduino pro mini few days and it worked without any problems. Once I have uploaded code to it, and it worked, but later it stop working. I have tried to upload code again but it won't. I thought that I was fried amega328p chip. So I decided to find what realy problem is. I also have other broken Arduino pro mini board that doesn't work, so I have tested it all. In two arduinos I have found that reset button is not working, so that was my problem, and I have solve it in this video. If you have all good connections and reset button is good, you can try too burn bootloader to your chip, that might be solution. avrdude: stk500_recv(): programmer is not responding
