How to wire a small quadcopter drone with resistor and breadboard (If possible)?
You need resistors where that article puts them, otherwise you could brownout the whole thing. You may be able to get away without a PCB, at the cost of reduced stability. Find or borrow the three resistors needed for the project, and then I recommend that you order both a large pack of 1% resistors as well as a variety of PCBs when you are able to.
