My second Xperiment in ELECT 10

so we hit the second day
i still havent given up lol :D
so today we learned a lot about  continuity testing, voltage testing, resistance testing and after mastering those we did all those test on our modified adaptors.
and then after making sure that there was no continuity on our adaptor and that our adaptor passes 5V
we connected it to a breadboard with a LED and a resistor on it and here is the beautiful result :D

and then to see the result of higher or lower resistance on the brightness of a LED i made this board on which each LED has a different resistor behind it and the furthest has the least resistance and here is the result

clearly the higher the resistance the dimmer the LED will be.
and then we calculated the least possible amount of resistance that we can put on the way of A LED
using the V=R*I
and finally we received our very amazing magic box to build our very own robot yaaaaaaaaay
