I've just bought an arduino 101 board and started playing around with it but I have a problem with sound sensor. Firstly - when I clap or do pretty much anything noisy, it stops serial monitor and computer make that sound it makes when you plug something into an usb. But it worked, at least until today. I made a sketch that lights up an led when I clap and it was working fine. But when I tried to make it work with Blynk(where you could turn on and off clapping), it started to freeze after few claps.
