My Arduino Blinks

I decided to toil with my Arduino UNO  which I have kept inside the cupboard for a while, the reason being that my system is really not in a good state.
Okay asked a friend for his system and he willingly gave it to me. I installed my Arduino environment on his system both the IDE and the Arduino Driver.
It was not so easy at first but through the tutorials on Arduino's website I got the blink sketch and uploaded it to my board. Tada, it blinked and now blinks whenever powered with battery.
Though I tried editing the code to change the frequency of blinking but the IDE crashed and continued to so.
Anyway not much bothered about that since that was not my own system so debugging the app on his system might result to unexpected results, so no more codes for now.

Arduino In Nigeria

Still wondering why some stuffs like this are still so hard to get within the country.
Why can't I get a clean Arduino UNO in any eastern town here as my friends in other countries would?
This type of material should by now in the country be readily available to any student who wishes to make use of them at any time and any place. Does is really mean we do not have importers in Nigeria who are already aware of the opportunities this kind of devices can offer electrical and electronic students, hobbyists, lecturers, the entire embedded community and even to Kidd that are passionate about embedded projects?
It actually took me a couple of months before I  was finally able to have this thing in my hand and it was not funny.
