Go To Lecture
Do Experiments as in the Syllabus
“ wire-by-numbers”
• three to six student in a Team
• one student, builds circuit, takes measurements,
fills out lab notebooks
• others texts friends & look out into space
• one student learns hands-on

the
Analog Discovery Design Kit
allow students to build and test a wide
range of analog and digital circuits
using their own PC without the need
for any other special test equipment.
6
Active learning –
learning by doing
helps engineering students
understand the process of breaking
down larger problems into smaller,
more easily solved parts without
losing the overall understanding of
the complete system.

the
Analog Discovery Design Kit
allow students to build and test a wide
range of analog and digital circuits
using their own PC without the need
for any other special test equipment.
19
This approach eliminates the time
and space limitations of traditional
university lab settings and allows
students more flexibility to
experiment with real circuits through
direct hands-on experience

Electrostatic Discharge Hazard
Electrostatic discharge (ESD) is the sudden flow
of electricity between two objects caused by
contact, an electrical short, or dielectric
breakdown. ESD can be caused by a buildup of
static electricity by tribocharging, or by
electrostatic induction.

Let’s Get Started !
Google “Analog Discovery Kit Digilent”
27
Scroll down page to waveforms
28
Mouse click on “Learn more”
29
Click on
30
Need about 38MBite HD space
MS Security Essentials will not be happy
31
Follow set-up wizard’s instructions
32

34
If you see this, the Discovery kit is
not plugged in to USB port
35
Unit was detected
“connect to device”
36
You are now connected
37
Download

Experence the WaveForms software
This can be done with or without the
Discovery kit , use demo-mode

Learning the ADK Leads (Analog Discovery Kit)
Solder-less breadboard use
Power Supply Operation
Voltmeter Operation
Series Circuits Measurements
Superposition Theorem
Homework problem
41
42
Time to take the ADK out of the box
and connect to a USB port.
Connect the Leads to ADK.
43
The Leads are Keyed
bottom view
color wires with white stripe on bottom, also bottom has small feet pads
44
Note keyway notch
45
Keyway pin
46
ADK top view with leads
plugged in
( note solid color wires are on top)
47
Leads are color coded
48
Leads we will be using today
49
To make things easer I use a rubber band to
keep the leads I am not using out of the way
Not used
Leads in use
50
Plug one end into the connector on the end of
the leads from the ADK
(may be using solid copper 24 awg. insulated
wires for leads with ends striped )
51
Now your lead from the ADK is longer and
you can plug the PIN end into your
solderless breadboard

Analog Discovery Design Kit
• Power Supply
– Two fixed voltages +5 volts / -5 volts, 50 ma. MAX
– Switchable ON / OFF commands
– Unit powered by USB computer port, (cable included)
55
With the ADK plugged into your computer
USB port, click on the “W” short-cut logo.
The status bar of the Waveforms Window
should appear and a red LED on the ADK
near the place the USB cable plugs into should
be on
56
You are now connected
57
If you see this window recheck your USB
cable connections and try again

Superposition Theorem
• Some circuits require more than one voltage or
current source
• The superposition theorem is a way to
determine currents and voltages in a circuit
that has multiple sources by considering one
source at a time
