Oscilloscope Probe into Arduino Board's Crystal Oscillator

This Arduino-compatible board shares the same physical dimensions and pin layout as the Arduino Uno board, and utilizes the familiar ATmega328P microcontroller.
In contrast to the official Arduino Uno SMD board, this version incorporates a different crystal oscillator.
Today, we'll use an oscilloscope to capture the power-up and startup waveforms of the microcontroller and the 16MHz crystal oscillator.
