What 'Essentials' Electronics Topic would you like to Learn More About?

Hi I have started with arduino a few months ago my knowledge off electronics is limited can you advice me on wear to start building more knowledge up and witch course to start .Thanks Nelson

nelson64 Hi, the First thing I would do is to scrap the Arduino's pitiful IDE and use Eclipse, I use just plain C with my Arduinos, but I still use the Arduino libraries for the most part. you can do this two ways:

first is to write using Arduino FrameWork ie. setup() and loop()  (which leaves a lot to be desired

The second is to write using C (you run into trouble with scoping rules with C++ ).

I normally keep one function on one page of code which is included  + its header file.

ie..

count.h

int counter;  // thsi could now be a Global but you will have to initialize it before you use it

file count_P.h

MaxCount = 8;

MinCount = 1;

#define UP 1

#define DOWN 0

file counter.c

#include counter_P.h

int counter.c ( int updown ) {

    switch (updown) {

        case UP: {  if( counter = MaxCount ) conter = MinCount;

                           else counter++;

        case DOWN:
