Guys, the Halloween is approaching. Are you prepared for the upcoming Halloween?
Do you know that the term “Halloween” is a shortened form from All Hallow’s Even, which it is the eve of “All Hallows’ Day” or “All Saints Day” in other form? It was a day of religious festival in various northern European Pagan traditions. The church is traditionally celebrated this day as the Vigil of All Saints.

Meanwhile, the ancient Gaels believed that on October 31^st, the boundary between the alive and the deceased would be dissolved. As the result, the dead become dangerous for the living by causing problems, example like sickness, damaged crops or murdering as well! In order to avoid from being a victim of the dead spirits, people were wearing costumes and masks on this day to mimic the evil spirits.

Today, you’ll have the chance to be involved in the Halloween eyes project. Basically, this project is quite simple, where a pair of spooky disembodied eyes will be rendered on a 4 5×7 dot matrix display. As a result, the Halloween eyes will blink every so often.

After you’ve done with the Halloween eyes, it’s time to put it in the bushes and scare your friends away lol

Does anyone here ever involve with Servo Tester 2 before? Well, if you didn’t know what this Servo Tester 2 all about, a combination of hardware and software is used to make a pulse width signal between 1 and 2ms. Technically, the signals will be used to control common R/C servos.

Today, you’ll have the chance to challenge yourself, by simply develop a smart and comprehensive Servo Tester 2!

The Servo Tester 2 can be generates two separate signals to drive two servos and it has its own sweep mode for stress testing servos. The LCD that being applied on this project is the 2×16 character LCD. Since this is a very simple interface, thus it can access all features with just a single rotary knob with the integrated push button!

Plus, the RS-232 connection will allow you to write your very own program and it can be used to control every feature of the tester.

Lastly, you’re allowed to use the Servo Tester 2 hardware and software because both of them are free. As a result, you can copy, build and use it as much as you want, as long as you didn’t use it to make any profit of it!
