i think it didnt teach enough on programming and making more complex stuff as much as it did showing you(and doing all the work for you) how to control an connect electronics.
Vague statement. Do you have a EE background? For sensors and LED strips and stepper motors and servo motors and stuff like that, both Adafruit and Sparkfun have a huge selection and most come with sample code and Arduino libraries if required.
Hooking up a LED requires knowledge of one electrical formula: E = I * R
E is voltage in Volts
I is current in Amps
R is resistance in Ohms
And that formula will serve you well for all simple DC calculations.
Another good formula is: P = I^2 * R
P is power in Watts
I is current in Amps
R is resistance in Ohms
Pick up a used textbook used for Industrial technicians. 99% of what you need is there... The other 1% is complex math needed for non-DC calculations and if/when you need, ask here and we will steer you.
