With that out of the way, I’m super pumped to say that I successfully used my Macbook Pro and a 433 MHz receiver as an oscilloscope to analyze the RF signal from a remote control for these inexpensive outlets. Please see my formal(ish) disclaimer for more info. I don’t know what I’m doing with electronics, I’m a total beginner, so you probably shouldn’t believe anything I write here without verification from a more credible source. This could possibly be unsafe and result in damage to your computer or your health.
Bottom Line: You can use your Macbook Pro’s sound card as an oscilloscope! Disclaimer
