i raise some of the questions and get some help form ppl online .(i will credit them in my report)
i never study physics and these circuit stuff so the whole project is very challenging

finally i made up a circuit suit my project and i think i am able to finish it.
i will post the circuit diagram later

simple ways to lit led

LED throwie

A simple led cube

DIY LED Reef Aquarium Light


but these only lite the leds up and not interactive

led circuit research

some easiest circuits

some complicated ones

bought some leds and switch for experiment

LED research

Got 2 common size 3mm and 5mm

different require differet voltage and so different resistors.

and they need different current or they wont be bright enougth.

I need to becareful about the choice of resistors so i wont burnt the leds.

some LED resistor caululator websites

they help me to know more about resistors needed

good flash website and books
