Girino - Fast Arduino Oscilloscope
It is an awesome project.Iam working on similar kind of projects,actually i am not that much good in Analog Electronics. I have some doubts,please help me1) what is triggering?2)why do we need to to give threshold voltage?arduino itself does the conversion right? Just like AnalogRead.
