I watched a ton of YouTube videos and reviews before deciding to try this neat little hobby out, and more often
than not people just used them bare bones; all nekked before God and everyone. Poor things. I wanted a case for mine. This
Zebra worked out fine.
Arduino Uno Zebra Case (Black Ice)
Note: off brand versions of the UNO may have some slight variance in IC placement and such. As a result, I did have to make a small
modification to the case so it would fit to my satisfaction - but it was just where the timing crystal just barely touched the inside surface
of the case. No big deal.

I wanted something with an analog input other than a thermistor or potentiometer, so I figured these would be responsive
enough for testing, learning and programming on that side of things. Plus I had never used anything dealing with Ultrasound, so hey,
it sounds cool... Not tested yet.
Kuman 5pcs Hc-sr04 Ultrasonic Distance Measuring Sensor Module kit for Arduino UNO Mega R3 Mega2560 Duemilanove Nano Raspberry Pi 3 Robot K18
By the description alone you can see it works with several platforms. I expect no issues with these - COUNT OF 5 modules.

This is the culprit that got me started in this mess to begin with. I was designing a circuit using a simple 555 timer and ran across this stupid
thing. I was instantly sold. But to program it, I would have to start with the beginning - and now here I am. This is the Atmel AT-Tiny 85 MCU. It's the teensy
version of the chip that is on the UNO and will handle the same programming. Dudes and dudettes - this is very cool.

The Aruduino UNO uses the ATmega328P processor and it is capable of keeping track of time. However, removing power from the development board kills the clock
and upon restarting so does the clock to a standard time. Not good for datalogging or anything else time sensitive. So I figured a RTC with backup power (the button battery) would be
a good idea. This one is also supposed to support charging of a Li-Ion CR2032 type cell. For more info on the ATMega238P's built in clock, go HERE for the official skinny from Arduino on
how to keep the clock running with a simple hack.

The developing/programming sofrware that most people download and use from the Arduino folks has a serial terminal viewer
that let's you check things out on your program while it is running. But I will also want human readable data feedback without having to rely
on being hooked up - four lines and twenty chars per line should be just great. And it's backlit (tested - WORKS GREAT).
SunFounder IIC I2C TWI Serial 2004 20x4 LCD Module Shield for Arduino Uno Mega2560
It says Mega2560 - but since it uses the I2c protocol it should work with anything that talks that handshake. Updated - it works just fine with the ATMega 328 mcu.

I have momentary button switches, toggle switches and all sorts of this and that for methods of input. But I've never messed around
with stepper motors or the like. To do so I will need some encorders. So I got few of each that you will see throughout this list. These were also just a
bargain...
CTYRZCH 5 PCS KY-040 Rotary Encoder Module Brick Sensor Development For Arduino TE173
From the feel of them (rotating) it seems like they have 20 positions throughout the 360d turn.

Since I plan on playing around with stepper motors (I have a project in mind for them) I figured I should get a really nice
encoder. This one has 600 positions (advertised) and I can't even tell the divits by feel when turning the rotor.

As of the time of this publication it went down a dollar from what I origianlly paid.

This was just a givien that I ran across on Amazon when looking into the Arduino stuff. 5 stepper motors, 5 controllers, and plenty of hook-up jumpers for each.
Kuman Stepper Motor for Arduino 5 sets 28BYJ-48 ULN2003 5V Stepper Motor + ULN2003 Driver Board + Dupont Wire 40pin Male to Female Breadboard Jumper Wires Ribbon Cables K67
Comes in a really nice clear plastic (not brittle) case and everything fits just fine without being jammed in.

Doing some research on stepper motors I discovered the smoothnees, precision, and noise level of a stepper motor was due largely
to the driver (controller) board that was interefaced to it. These are supposed to be better than average.
Hobbypower A4988 StepStick Stepper Motor Driver Module + Heat Sink for 3D Printer Reprap (pack of 5 pcs)
I paid $7.27 when I purchased them - they went up a little...

I got these because the cost was less than ten bucks for five. One of the pictures has a disturbing solder point - but I took the chance and ordered
them - they have yet to arrive. Update this when that happens.
Alloet 5Pcs Mini Breadboard Prototyping Prototype Shield ProtoShield for Arduino UNO
These have yet to arrive. At the price, even if the PCBs are poor quality - the five breadboards alone are worth the $9.79 I paid for them.

A nice stepper motor with decent holding torque. I don't see it in the description at the time of this publication, but memory has me checking
this thing out at 200 positions. I'll find out and post here when I test it.

Got these for $4.29 - and there was no shipping for some reason. Anyway, I figured I might need a few so I got some.

Whenever you go shopping on Amazon - don't just get the first thing that shows up. This was several pages [Next->] when I found
the whole set for $7.99 - One or two reviews were negative saying they were 'resistors' or wouldn't conduct. Mine are just fine. But at the time
of this publication they are out of stock on this link...
