Dan,

I have seen the Makerfaire (Maker Lab members) types using Arduino's UNO's to do projects that
do NOT know how to program in the 'C/C++' language. That they simply cut and paste someone else
Arduino sketch verbatim into the Arduino IDE and install some optional library files per the
'cookbook' documentation of prior project and upload the compiled output to the target board.

They have a working project. (assuming they did follow closely enough to the 'cookbook' details)

A few years back I wanted to learn with 'deeper' understanding a 'target' board so I choose the
Texas Instruments (TI.com) 430 CPU and an affordable Lanchpad(tm) eval board (not this exact
board but similar) and used the Eclipse IDE not the simpler Arduino IDE. The language chosen
was ANSI 'C' (99) language.

link to similar target board:

I didn't start by expecting the 'students' to have knowledge of host development tools and the
details of the TI 430 hardware.

Started with a (pre-class) of about 8-weeks to learn the 'C' language at the Linux CLI (aka the
command line). The editor was the student choose and was usual either the 'nano' or 'vim' editor.
I helped by providing a few example GNU make files to make it of a typing class. :-)
Topics were: numbers (various bases), variables, standard i/o, conditional flow control, looping,
characters and strings, file i/o, structures but no real deep study of advances pointer stuff.

Maybe the most advanced topics was a demo of a single and double linked list.

The first phase had about 8 student that included no electronics technicians or engineers. I
then followed on with phase 1 (part B) about 2 weeks of follow up of simple schematic circuits
and intro to simple logic gates and truth tables for (AND, OR, NOT, XOR, NAND, NOR gates and a
free-running, one-shot and a J/K flip-flop)

A *flip-flop* is a bistable multi-vibrator and not Florida beach-ware.

I am NOT really a teacher but more of a technical mentor.
