Hello, I am new to this forum and still learning about some aspects of electronics. I have purchased and installed a USB oscilloscope and am trying to learn how to use it one step at a time. I have set up an Arduino Uno with a PWM sketch to cause an LED to pulse. That part works just fine. However when I connect my Oscilloscope I get a wave form like the one shown in the attached file. As a complete newbie to the oscilloscope I am trying to understand why I am not getting the square waveform I was expecting. I dont know if it is the oscilloscope, its settings or the Arduino setup I am using which is pretty much a very standard setting as is using the basic Fade sketch available in the Arduino GUI I am using.
Sure hope someone can help as I have tried everything and just keeping get ting further lost
