 =====Objective=====
-To expand upon our previous efforts, through wiring up additional LEDs and generating a "binary counting" pattern of lit LEDs on your pi.
+To expand upon our previous efforts, through wiring up additional LEDs and discovering what pattern they activate in, given the provided program.
 We also further utilize time constraints, tying project credit to your starting on the project before the deadline (so be sure to plan accordingly!)

 ====(1) T-cobbler and data cable====
 In your kit should be a T-shaped device (known as the "T-cobbler" with some aspect of pin names silkscreened on it, and a 40-pin ribbon cable). Colors may vary, but essentially it looks like this:

 Take note of how everything is being plugged in, and what connection on the T-cobbler is being utilized.

 <WRAP info>Before you seek to actually test your circuit, please get verification to proceed from the class channel on discord by posting a clear picture of everything. There are MANY moving parts, and especially as we have our first exposure, it is best to insert as many quality control checks as possible to ensure the greatest chances of mistakes are mitigated.</WRAP>

 ====Testing connectivity====
 To verify whether everything is hooked up correctly (including the correct positioning of the LED), please try the following:

 If you get no activity out of the LED, try reversing it and try again.
+With an expanded set of LED circuits, be sure to test the operation of each one.
 =====Program=====
 It is your task to compile, run, expand upon, and understand a program to interface with a set of LEDs (light emitting diodes), a nice software-hardware connection, on your raspberry pi.
