LED - Interesting Observation

So today I was curious to know what's the voltage drop of LEDs with different colours.

As I made the connection, i.e the positive tip of multimeter to the positive lead of the LED and vice-versa, the LED lit up.

Astonished I was, but a moment later I realized that I just got electric shock from the connection my finger made with the close circuit.

Heh, good lesson for today.

Tomorrow's plan - GET YOUR ROBOT WORKS, WOMAN!

Arduino Experimentation Kit from OOMLOUT

So tonight, I've officially "graduated" from all the 11 lessons from Arduino Experimental Kit from OOMLOUT.
In fact, this is the first Arduino kit I've ever had.



I found this kit is a very very good start for a beginner like me, who suddenly wakes up in the morning and decides to invest her savings to learning electronics during the xmas break.

All the instructions are very clear, with the aid of the colourful-printed-circuit diagrams. And also my technical background as an electrical engineering student helps me a lot in understanding stuff. However, there are still few hiccups along the way, for example, my temperature sensor heats up rapidly that it started to smell like smokes. It freaks the shit out of me as I thought I might have burnt my Arduino board for some reason. And the temperature recorded at my Serial Interface was almost 240 degree Celsius! The datasheet says that the maximum operation of the temperature sensor, TMP36 in this case, is only 150 degree Celcius! @_@


I dunno what had happen I'm not daring enough to redo the whole circuit again.

The second thing is that the relay is so sucky that it doesnt stick into the breadboard. You have to press it real hard to see the output of your circuit. It's a lil bit sad that I couldn't explore much about the relay coz apparently it is very interesting device, and most probably, very highly important in my future robot project. Or not.

So I totally recommend this kit for any beginner out there who wanna play with microcontrollers. Thanks to Oomlout for such a great kit! =)

First Entry!

So I'm basically done with this semester 2 days ago, hooray! =)

Now here begins my exploration for this amazing electronic world.. And the sole reason for the existence of this blog is because I read everywhere on the internet about open-sourcing, taking and giving it back to the others, and also documenting projects so that it would be beneficial to other people.

I hope my exploration in this field would benefit others in any ways. Cheers.
