If A=0 and B=1, set A to 1
If A=0 and C=1, set C to 0

if (B=0 and C=0) OR (A=1 and B=1 and C=0), set C to 1
GOOD NEWS! I'm done with my instructions and report for the project! About time . . .

Keep in mind that the model shown in this video is slightly outdated from the newer instructions (no blue grabbers in the back).
