Piezo Element
What it Does:
A pulse of current will cause it to click. A No. of Leads:
stream of pulses will cause it to emit a 2
tone. Things to watch out for:
Identifying: - Difficult to misuse.

Potentiometer
What it Does: No. of Leads:
Produces a variable resistance dependant 3
on the angular position of the shaft. Things to watch out for:
Identifying: - Accidentally buying logarithmic scale.
They can be packaged in many different More Details:
form factors, look for a dial to identify. http://ardx.org/POTE
IC (Integrated Circuit)
What it Does: No. of Leads:
Packages any range of complicated 2 - 100s (in this kit there is one with 3 (TMP36) and
one with 16 (74HC595)
electronics inside an easy to use package.
Things to watch out for:
Identifying:
- Proper orientation. (look for marks showing pin 1)

Photo Resistor
What it Does: No. of Leads:
Produces a variable resistance dependant 2
on the amount of incident light. Things to watch out for:
Identifying: - Remember it needs to be in a voltage

RESISTOR COLOR CODE LEAD CLIPPING
Some components in this kit come with very long wire
leads. To make them more compatible with a breadboard
a couple of changes are required.
LEDs:
Clip the leads so the long lead is ~10mm (3/8”) long and
the short one is ~7mm (9/32”).
Resistors:
Bend the leads down so they are 90 degrees to the
cylinder. Then snip them so they are ~6mm
(1/4”) long.
Other Components:
Other components may need clipping.
Use your discretion when doing so.
