Hello Everyone :)



I am totally new to Quadcopters, i am working on a project to build this , I am using HobbyWing SkyWalker 40A esc ST2212 brushless motor and a 2200mAh 20C lipo battery, i have purchased the APM 2.5 kit , 

Now for my first experiment i am using Arduino uno to test the motors , and i need some help, can someone please provide me a simple arduino sketch  for me to just start on this project soon, that can be used to calibrate the esc and then i shall be able to move the motors as well , i shall be very thankful for this,

i have tried it on my own and i have lost my battery twice , i connected ESC + motor + arduino uno , i think i did right but the battery went out of the order twice , i dont know , i am totally new to all of this , and i am really not understanding what is happening there with me , any one can help me about this please ?

i shall be very thankful
