As per my previous post, I started researching electronics as a hobby. As I dug deeper,
I discovered Arduino, a micro-controller board designed for
layperson, hobbyists and artists. A search on YouTube resulted in
some amazing projects created by people with no formal background in
electronics or computer science.
I went through
several tutorials and was very reassured that I could make sense of
at least some things that the tutorials dealt with. I decided to give
Arduino a try.
The first thing I
did was to visit the official website which is an excellent place for
everyone from beginner to expert. Since Arduino is an open source
project, the website is very friendly. The volume of information
about the platform could be overwhelming in the beginning. The best
way is to take is slow and concentrate on the basics.
Where to begin?
Like every open
source project, Arduino could be as simple or as complex as you wish.
Hence, it could be down right scary for beginners who have no idea
where to start. As I browsed about the projects and went through
tutorials, I developed a plan of action for myself. So far it has
worked well for me.
The Action Plan
Step One: Get an Arduino
Almost every website
I visited wanted me to buy their special Arduino kit with 25 other
components. The cost varied between USD 60 to 200. Add in shipping to
Karachi and the cost went up another fifty bucks. I decided to buy
from a Pakistani vendor and was pleasantly surprised to see several
online stores offering the whole range of Arduino related products.
The cost ranged from PKR 1200 to 3500.
I was not sure of
anything at this point and thus opted for a second hand Arduino which
I bought for PKR 800. The deal included the USB connector cable. I
asked the guy for some LEDs and resistors which he threw in for PKR
100.
Going the OLX way is
risky. I got lucky and got a board that actually worked. However, it
is best to buy a new board once you think you will continue with the
hobby.
Step Two: Get Assorted Tools and Stuff
A breadboard is
essential during the initial learning process. You could easily
prototype circuits without worrying about insecure or loose
connections. In addition, it is good to have the following tools and
stuff:
Tweezer to handle
small components such as resistors. (PKR 40)
A wire stripper to
make jumpers. (PKR 400-1600). Get a cheap China brand.
24 AWG wire for
connections. Just ask for the wire used in breadboarding and the
shopkeeper would understand what you want. (PKR 13-17 per meter)
A portable light is
essential to illuminate the work area. Get a small chargeable light
from one of the street stalls. Get a small chargeable light from one
of the street stalls.
Electrical
Components
LEDs in several
colors. Get 5mm ones with long legs. Avoid smaller 3mm LED because
they are difficult to use with their small legs. Get at least a dozen
so that you could play with patterns. (PKR 3-4 per LED)
330ohm resistors are
good enough to protect LEDs when using Arduino in breadboarding.
(PKR 2-3 per resistor)
As you progress, you
might need additional components such as pushbuttons, LDR, IR LED and
shields. I recommend buying as the need arises.
Step Three: Get a Good Book
Beginning Arduino,
2nd Edition By Michael McRoberts is a great place to start learning.
The book starts slowly and explains everything in detail. The best
thing abut Arduino is that you immediately see the fruit of your
labor in the form of blinking LEDs.
