I am currently doing my first arduino project and i am having trouble finishing it.
I have a 3s lipo battery connected with an esc (120A) that is connected to a motor (270KV). From the esc i am connecting two jumper cables that goes to GND and pin 9. I do not have a jumper cable on the red wire from the ESC.
This is how it looks:
Below you can see a link to a sketch that I found online. The only difference compared to my schematic is that I have an Arduino Uno.
When I insert the battery and switch the ESC to "on" the ESC starts up correctly and the fan starts to go. But the arduino does not get any power. It is still "OFF".
I also noticed that my motor has 4 cables. 3 "bigger" cables that goes to the ESC's 3 big cables. And then a 4th one hanging loose right now because i do not quite know what to do with it. I also noticed there is a hole in the ESC where I can insert this. The hole has 6 "inputs" however where as the loose wire from the motor has 5. Therefor I am a bit concerned if that should be connected there or not.
So to summarize, the problem is that the Arduino does not turn "ON" with my current schematic. Any help, tips is very appreciated!!
