Arduino-Type Microprocessors

This is a notional category. I'm saying 'Arduino-Type' to cover a whole raft of differently named and featured microprocessors, some of them costing under $10. There is also a thriving ecosystem of Arduino clones.

A important point that is often lost ( lost on non-EE degreed me anyway ) is these beasts can work with a range of voltages, typically between 7V and 15V. Most computers take only 5V and are very picky about that. Most microprocessor devices are far more electrically robust than a computer. Maybe think of them as sophisticated current switching devices ...

I had not planned on doing intense Arduino development and still don't, but I got a simple ( and cheap ) Inland Developer DIY kit at Micro Center and it's been an interesting few months understanding it and getting it going. Well worth the effort, especially for HomeAutomation.

https://www.arduino.cc/en/Guide/Introduction

Arduino is an open-source prototyping platform based on easy-to-use hardware and software. ...

... As soon as it reached a wider community, the Arduino board started changing to adapt to new needs and challenges, differentiating its offer from simple 8-bit boards to products for IoT applications, wearable, 3D printing, and embedded environments. All Arduino boards are completely open-source, empowering users to build them independently and eventually adapt them to their particular needs.

It's a huge community, starting to generate megabucks of hardware sales, which is no small achievement in the open-source open-licence community.

https://www.sparkfun.com/products/11229 - Arduino Ethernet - $60

The Arduino Ethernet is an Arduino development board with the Wiznet Ethernet interface built in on the same board! It has 14 digital input/output pins, 6 analog inputs, a 16 MHz crystal oscillator, a RJ45 connection, a power jack, an ICSP header, and a reset button.

...

To make room for the Ethernet interface, they removed the USB-serial driver so you will need an FTDI breakout or similar device to upload your Arduino sketches. Also, Pins 10, 11, 12 and 13 are reserved for interfacing with the Ethernet module and should not be used otherwise. This reduces the number of available pins to 9, with 4 available as PWM outputs.

https://www.sparkfun.com/products/12053 - Arduino Yun - $75

... The first Arduino Yun is the combination of a classic Arduino Leonardo (based on the Atmega32U4 processor) with a WiFi? system-ona-chip running Linino (a MIPS GNU/Linux based on OpenWRT). Arduino embedded the Linux machine directly on the PCB of the Arduino Leonardo and connected the two so that from Arduino it’s very easy to run commands on the Linux side and use it as an Ethernet and WiFi? interface.
