Dr.Duino Diagnostic Equipment Kit
Turn Your Dr. Duino Explorer Into a DMM & Basic Oscilloscope.
As seen in Nuts & Volts Magazine.
The kit itself is made up of two separate parts, the Dr.Druino Explorer Kit and an online course called the Diagnostic Equipment Course (DEC).
The DEC is what transforms the Dr.Duino Explorer into an absolute beast of an Arduino shield.
The course has you perform several experiments which teaches you how a Voltmeter, Ammeter, Ohmmeter, Continuity tester and basic scope works.
Normally, Arduino-based kits will just provide you with a bunch of code and some schematics, but that's where this kit is just warming up.
It starts off with a neat concept which the folks over at Dr.Duino call "Layered Learning", which is what they use to teach you the concepts of how Analog to Digital (A/D) converters work.
This layered learning approach really helped me understand what the microcontroller inside the Arduino Nano is actually doing to perform its A/D magic.
They provide an excellent video tutorial of how SAR type A/Ds work. (SAR is short for Successive Approximation Register.)
From there, they layer on more and more complex topics slowly.
Each topic builds upon the previous lesson, which really helped me understand how DMM's and scopes work.
Once you understand how the hardware works, it makes creating any project which requires A/D conversions a breeze.
Here is what you will learn!Lesson 1
Discover the difference between Analog and Digital Signals without tons of theory and explained in a very easy to understand way.
Review how the Analog to Digital (A/D) converter onboard the Arduino Nano works from a hardware vantage point. Includes a deep dive into the most common type of A/D used called a Successive Approximation Register (SAR).
Scaling Factors, Resistor Divider Networks, Ohms Law & Power Calculations, Limitations of a 10-Bit A/D

What else Do You Need?
Aside from your Dr.Duino Explorer and the DEC the only other things you'll need are some assorted 3-Watt resistors and dupont wires used to wire up some test circuits.
These are not included as part of the kit but chances are, you probably have them on hand anyway.
You might be wondering why 3-Watt resistors are required.
Well, that's because part of the DEC has you build a very impressive Ammeter which is capable of measuring up to a maximum of 106 mA.
If you were to drive that much current through a typical 1/4 watt resistor, well... let's just say that you'd be able to cook an egg with it.
In the course, they do provide links so that you can pick them up.
