The independent variables are the variables that cause the effects you're investigating

the dependent variables are the effects... variables that change as a result of the independent variables.

I think of INdependent variables being like the INputs to the experiment

from reading the text you should be able to tell what the cause variable is and what the effect variables are.

Things that you predict might have an effect on the dependent variable if they were allowed to change... you control them by not allowing them to change.

e.g. in this experiment you might to decide to control the colour of light used by using the same light source for every angle rather than picking a random coloured LED out of the junk for each angle - or controlling the temperature by checking that it remains constant throughout the experiment with a thermometer.

TBH these variables can seem trivial and just involve not doing crazy things like swapping LED colours for no reason but it's worth giving them a bit of thought and making sure you mention some in your report...
