DC Motor
What it Does: No. of Leads:
Spins when a current is passed through it. 2

This one is easy, it looks like a motor. - Using a transistor or relay that is rated
Usually a cylinder with a shaft coming out for the size of motor you're using.

Hobby Servo
What it Does: No. of Leads:
Takes a timed pulse and converts it into 3
an angular position of the output shaft. Things to watch out for:

ELECTRONICS IN BRIEF
No previous electronic experience is required to have fun with this kit. Here are a few details
about each component to make identifying, and perhaps understanding them, a bit easier. If
at any point you are worried about how a component is used or why it's not working the
internet offers a treasure trove of advice, or we can be contacted at [e-mail]
COMPONENT DETAILS
LED
(Light Emitting Diode)
What it Does: No. of Leads:
Emits light when a small current is 2 (one longer, this one connects to positive)
passed through it. (only in one direction) Things to watch out for:
Identifying: - Will only work in one direction
Looks like a mini light bulb. - Requires a current limiting resistor

Resistors
What it Does: No. of Leads:
Restricts the amount of current that can 2
flow through a circuit. Things to watch out for:
Identifying: - Easy to grab the wrong value (double
check the colors before using)

Transistor
What it Does: No. of Leads:
Uses a small current to switch or amplify a 3 (Base, Collector, Emitter)
much larger current. Things to watch out for:
Identifying: - Plugging in the right way round (also a
current limiting resistor is often needed on the base pin)
Comes in many different packages but you

Diode
What it Does: No. of Leads:
The electronic equivalent of a one way 2
valve. Allowing current to flow in one Things to watch out for:
