Nguyen-PM-1 hour- 8 bit computer project

After watching the video of 555 timer, I found out that it was more complicated than what I had learnt. Then, I decided to look for electrical class to learn, and I found an electrical engineering class on Khan Academy. https://www.khanacademy.org/science/electrical-engineering

I completed the instruction, and actually understand more about the current, voltage and power.
