--Bare Conductive Touch Board
The Touch Board by Bare Conductive gives you the power to
interact with the world around you by turning almost any conductive material or
surface into a sensor. Touch Board is a tool to make your projects interactive,
responsive, smart or just fun. It’s designed as an easy-to-use platform for a
huge range of projects. Touch and it will play sound!
--Round Force Sensing Resistor (2 Pack)
Force Sensing Resistors, or FSRs, are robust polymer thick
film (PTF) devices that exhibit a decrease in resistance with increase in force
applied to the surface of the sensor. This force sensitivity is optimized for
use in human touch control of electronic devices such as automotive
electronics, medical systems, and in industrial and robotics applications.
--Pulse Sensor AMPED for Arduino
Pulse Sensor AMPED for Arduino makes pulse measurement very
simple. Pulse measurement can be a very useful thing. Doctors have employed the
use of pulse measurement for hundreds of years to determine stress, relaxation,
physical fitness levels, medical conditions, and more. This information is easy
to gather using tactile measurement; you can determine your pulse rate by
touching your arteries in your wrist or neck.
--PIR Sensor
The PIR Sensor detects motion up to 20 feet away by using a
Fresnel lens and infrared-sensitive element to detect changing patterns of
passive infrared emitted by objects in its vicinity. Inexpensive and easy to
use, it's ideal for alarm systems, motion-activated lighting, holiday props,
and robotics applications.
--Grove - Moisture Sensor for Plants
The Grove - Moisture Sensor can be used to detect the
moisture of soil or judge if there is water around the sensor. Let your plants
reach out for human help! Just insert into the soil and see if your plant needs
water. I think Ivette needs this.

something. What does it do? .5 points
--SparkFun Car Diagnostics Kit Retail:
This board allows you to interface with your car’s OBD-II
bus. A wealth of information can be obtained by tapping into the OBD bus,
including the status of the malfunction indicator light (MIL), diagnostic
trouble codes (DTCs), inspection and maintenance (I/M) information, freeze
frames, VIN, hundreds of real-time parameters, and more.
7. Find 5 different motors and describe each look up what
they might be used for. Please tell me if they are DC motors, servo motors,
AC/DC motors or stepper motors. 3 including descriptions
--Small Stepper Motor
These small steppers are a great way to get things moving,
especially when positioning and repeatability is a concer
--Stepper Motor - 29 oz.in (200 steps/rev, Threaded Shaft)
These steppers have a threaded shaft, which allows them to
be used as a linear actuator. As the motor runs, it moves along the shaft at a
specific rate of 1cm per 5 full rotations. These are a good choice for linear
motion where precision and repeatability are important.
--Servo - Generic (Sub-Micro Size)
Here is a simple, low-cost, high quality servo for all your
mechatronic needs. This servo is very similar in size and specifications to the
Hitec HS-55. This little guy is able to take in 6 volts and deliver 20.8 oz-in.
of maximum torque at 0.10 sec/60°
--Servo - Generic High Torque Full Rotation (Standard Size)
A simple, high quality continuous full-rotation servo motor.
This servo is able to take in 6 volts and deliver 66.7 oz-in. of maximum torque
at 70 r/min.
-- Hobby Motor - Gear
The motor has a normal operating voltage range of 1.0 to
3.0VDC but can handle a max load of up to 12VDC and a no load speed of 6600±10%
RPM (@1.0V DC, 110mA).
8. Find 3 types of camera or optical devices. 1.5 points
9. Find three devices that deliberately (sound production is
part of their function) produce sound and tell me what they are. 1.5 points
--SparkFun SparkPunk Sound Kit
The SparkFun SparkPunk Kit is a sound generator made in the
spirit of the Atari Punk Console. Rather than simply recreating the Atari Punk,
the SparkPunk is a new design that springs from a similar foundation. It starts
with a dual 555 timer IC, then adds a second tone source, sub-octaves and a
bandpass filter. With all of the knobs and switches, a lot of tonal variations
are possible. As a through-hole kit, the SparkPunk can also be easily extended
and modified, expanding the palette of tones even further.
--WonderBeeps
The WonderBeeps board is a really simple way of adding
wireless capabilities to your next project. Simply connect a standard electret
mic, supply 3-5VDC and play the Beeps! The Beeps are transmitted at around 8Khz
so they can be heard but they can be embedded within other sounds to make them
almost unnoticed. Each transmission only takes about half a second. You can
download the Beeps as files or install the WonderBeeps iPhone App.
--Electret Microphone
Small electret microphone. Useful in acoustic and audio
applications.
--Bare Conductive Touch Board
The Touch Board by Bare Conductive gives you the power to
interact with the world around you by turning almost any conductive material or
surface into a sensor. Touch Board is a tool to make your projects interactive,
responsive, smart or just fun. It’s designed as an easy-to-use platform for a
huge range of projects. Touch and it will play sound!

10. Find five different kinds of potentiometers or variable
resistors. What is their range of voltages? What are they used for? 3 points
--Trimpot 10K with Knob
Standard Resistance Range: 10Ω - 5MΩ
Perfect for your next LCD contrast adjuster, opamp setting,
or volume level.
--Rotary Potentiometer - 10k Ohm, Linear
Total Resistance Range: B: 5KΩ ~ 1MΩ
An adjustable potentiometer can open up many interesting
user interfaces. Turn the pot and the resistance changes. Hook the center pin
to an ADC on a microcontroller and get a variable input from the user.
--SoftPot Membrane Potentiometer - 200mm
100Ω to 10,000Ω
Can be used as an accurate positional indicator for CNC head
positioning, variable user input (volume level input for example), straight
user input (multiple button areas translate to given resistance levels), and
many other applications.
--SparkFun Touch Potentiometer
The variable resistor offers a completely programmable value
of resistance, between the A terminal and the wiper or the B terminal and the
wiper. The fixed A to B terminal resistance of 20 kW, 50 kW, or 200 kW has a
nominal temperature coefficient of 35 ppm/∞C. Unlike the majority of the
digital potentiometers in the market, these devices can operate up to 15 V or
±5 V provided proper supply voltages are furnished.
--Slide Pot - Motorized (10k Audio Taper)
Total resistance 10KΩ±20%
These motorized sliders are very cool. Each is essentially a
standard slide pot which is belt-driven by a small motor. The slide contains
two separate 10k audio taper potentiometers so that you can use one as
servo-feedback in order to read the position of the slider and use the other to
control whatever your target is. There is also a touch sense line which is
electrically connected directly to the metal slider tab so that you can
interface the slider with capacitive touch circuitry.
