I'm just getting a start learning about electronics, and purchased a new oscilloscope -- a DreamSource Lab DScope U2P20 4, which uses the open-source DSView software 5. I built a simple 555 timer from page 7 of the Engineers Mini-Notebook: 555 circuits 6, and I'm getting an unexpected result from the scope. (Note: I added a 0.1uF ceramic capacitor between pins 1 and 8 due to noise from my power supply.)
My question is, is this an electronics problem (my circuit needs improvement), an oscilloscope software problem (rendering poorly), a hardware problem (I chose the wrong scope), or is it normal (an education problem on my end)? What can I do to get better results / visualization of the data?
Thanks much for helping a rookie learn!
