8051 - Automatic Room Light Controller with Visitors Counter

1 and a half month, finally the project has been done. This is the "Automatic Room Light Controller with Visitors Counter" project using Atmel 89C51(40 pins) from Intel 8051 family series.

The excitement after finishing the project is so indescribable. As the team feel so frustrated keep on troubleshooting the problems that caused the project not working. Even if you inquire Mr. Lecturer, he will always gives you the very "meaningful" idiom.

Student : Sir, we've done this this that that. Why still not working?
Lecturer : You just try this try that, try until it works.
Student : Cannot. It might burn the components.
Lecturer : Yeah. The more you burned, the more you learned.

Thanks for the idiom caused me burned out 2 infrared and 2 transistors. You think is cheap? Hell NO! We has spent around 160 bucks for the project though it can be done within 100 bucks.

Let's see how was the project transformed from a Zero to a Hero.
