As an electronics engineer
These extra components are needed to increase speed and stability for exected uses
So that ROMS can be trusted as a security device by the user

continuing from #2

So there is the full layout for the pins. With this in mind, I am now proceeding to remake

Eagle Cad here I have added an image of the 16 MHz Crystal connected to ground

000002_Selection

GIT[added 16mhz +grounding]

Crystal Oscillator work of the Piezoelectric effect. The Crystal needs to be connected to ground as crystal need grounding as when the crystal vibrates it can send a signal back down the connected wires to the ground nullifies these signals by redirecting them to ground The process of Grandma goes to a 20 microfarad Ceramic capacitor.
They provide a square wave signal which determines the time required for each T state

3.3v is Good for a max of 8 MHz
5v is Good for a max of 16 MHz

000003_Selection
GIT[added 16mhz crystal + grounding]

Here added is part of the Electrical relationships between VCC

GIT[added .gitignore so that the temp .s#1, .s#2 files dont get uploard to upstream git repo]

000004_Selection

Added reset headers that can be shorted to reboot the IC

GIT[Start of NRF24lo1 hook up & LED]

next up #6

it should be noted that I will be running at 5v to allow my Atmega328p to run at 16 MHz giving me double the default processing speed and in turn quick reaction times removing one potential bottleneck, which is a critical consideration when time is at the essence do with security
