Sypnopsis
This workshop intends to expose participants to a much
simpler approach to understand its working based on
practical problem-based approach.
Enable participants to gain real-world experience inusing microcontroller to monitor and control engineering
processes and develop competent skills in design.
It has been specially designed for beginners and
educators

Anonymous on MAKE:
Arduino is great because it can give you results
right away, and quickly build your confidenceand understanding. Confidence is the only real
currency of innovation after all. Once you have
that, you can move on to more sophisticated
projects. But without an easy-to-understandentry point, youll never get there at all.

Components: LED
LED (Light Emitting Diode)
What it Does: Emits light
when a small current is passed
through it.
Leads: 2 (one longer, this oneconnects to positive)
Things to watch out for: Will
only work in one direction
Looks like a mini light bulb. -
Requires a current limitingresistor

Resistors
What it Does: Restricts
the amount of current
that can flow through a
circuit.
Leads: 2 Things to watch out
for: Easy to grab the
wrong value
Cylinder with wires
extending from eitherend. The value is
displayed using a color

Potentiometer
What it Does: Produces a
variable resistance dependant
on the angular position of the
shaft.
Leads: 3 Things to watch out for:
Identifying: - Accidentally
buying logarithmic scale.
They can be packaged in
many different form factors,look for a dial to identify.

Pushbutton
What it Does: Completes a
circuit when it is pressed. 4
Leads: 4
A little square with leads out
the bottom and a button on thetop.

Integrated Circuit (IC)
What it Does: Packages any
range of complicated
electronics inside an easy to
use package.
Leads: 2 100s Things to watch out for:
Proper orientation. (look for
marks showing pin 1)
Identifying: The part ID is
written on the outside of thepackage. (this sometimes
requires a lot of light or a
magnifying glass to read).

Photoresistor
What it Does: Produces a
variable resistance dependant
on the amount of incident light.
Leads: 2
Things to watch out for:Remember it needs to be in a
voltage divider before it
provides a useful input.
Usually a little disk with a clear
top and a curvy lineunderneath.

Piezo Element
What it Does:A pulse of
current will cause it to click. A
stream of pulses will cause it to
emit a tone.
Leads: 2 Things to watch out for:
Difficult to misuse.
In this kit it comes in a little
black barrel, but sometimes
they are just a gold disc
