I have 4 motors connected to their own ESC (that is connected to a power distribution board), how do I connect this to Arduino uno? (Drone) I am currently working with a bigger drone that I want to connect with an arduino uno.

The motor and ESC that are already soldered together and connected are these: https://hobbyking.com/en_us/mt1806-brushless-combo-include-esc-5030cw-ccw.html

I have also connected it to a power distribution board where I succesfully can connect my 3s lipo battery.

What is currently missing is where I should put the 3 pins on each ESC onto the arduino board. So there are 12 pins in total.

The color on the 3 wires on each ESC are: yellow, red and brown.

Yellow is the signal if i am not mistaken and those should be connected on the PWM pins where I control each motor in the code.

When it comes to the red it is + power and should I ignore to connect these pins? I would like for my battery to power both the motors and the arduino so of course I would prefer to connect it to the arduino uno if it is possible.
Here are just some clarifications for you:


Signal pins don't have to be connected to PWM pins. AFAIK, any digital pins should work.
All grounds togheter! Glad you got that right!
Connect VCC of ESCs directly to the power supply.
Connect power supply to VIn of Arduino (not 5V because you are going to grill it!)




Uptdate


Yes, you can probably solder all the VCC wire of the ESCs togheter.
By power supply, I meant connecting it directly to the battery.





To power the Uno, connect the battery+ to the VIn pin of the UNO.
