Weirdness on Oscilloscope?
« on: June 13, 2015, 10:08:55 am »
Hey guys! So, this is my first time really working with an oscilloscope so go easy on me.

I have it hooked up to an arduino doing PWM. As I increase the duty cycle, everything is fine, until it gets too high. Then the signal shown on the display gets all weird.

I was wondering if you could tell me the cause of this. Thanks!

Mmh, I was able to get it to act normally by messing with the trigger a bit. Thanks. Now I need to go research this so I can understand it...
