Finally...I can do the experiment myself successfully!
 hmmm...actually it is not but almost if i got the readings more accurate
I was feeling so excited and wanna to cry but I hold it back...hahaha
well I didnt have the time to complete the report by the time but it was better than the last time!! that I copy the readings of someone when I fail the experiment!
 FRIENDS where are you !
I want to hug you tight and told you my happiness!
