Using LEDs As Precise GPIOs

In this video, we're looking at a technique for precisely analyzing signals from firmware when all you can do is blink a LED. By writing to an LED as if it were a typical GPIO, and building a surprisingly simple receiver, we can probe signals with an oscilloscope without even touching the board! =[ 🔗 Links 🔗 ]= 🗣 Discord: https://discord.gg/FPWaVgk ⭐️ Patreon: https://www.patreon.com/lowleveljavascript
