quadrotor

Step 19

Solder the speed controllers to the motors so that the propellers spin the right direction. 

Refer to the wiring diagram for electrical connections.

Notes on diagram wiring :

-We used additional header pins to all connected to VCC to create additional 5V pins. We did the same for ground.
-1 speed controller’s 5V power from the 3-wire-connector must go to VCC on the Arduino. This connection supplies the power for the entire board.
-All 4 speed controllers’ ground wires must connect to the Arduino’s ground pin(s).

Is it necessary to use an esc programming card? Where you able to use the esc's right out of the box without having to modify/reprogram them?

I'm buying an Arduino Uno. I'm not sure if you know, but would you connect the same pins on the uno? Or do they have numbers and voltage correlations?

The Arduino Uno has a lightly different layout then the Pro Mini being used here. One plus is that you can skip that 3.3v regulator because there is one on the board already. You'll notice that there is a pin labelled "3.3v" to which you can connect the corresponding 3.3v port on your sensor board.

So the pins for the sensor board the line up as such;
3.3v = 3.3v
GND = GND
Gx4 Y = Analogue5
Gx4 X = Analogue4
Gx4 Z = Analogue3
A Z = Analogue2
A Y = Analogue1
A X = Analogue0

The rest of the pins should correspond plainly to the ones on your UNO
Digital pins 6,7,8,9 to the control pin on your ESCs. Human controls are on pins 2,3,4,5 to your receiver. Personally I am using an Xbee module instead so I will not be using that last set.

hey, I've heard about Edgerton Center. I've never come down because I couldn't find much info on the site.

A lady, I can't remember her name brought it up at the st louis airport after the FIRST championship. I'm interested in coming to check out what you guys do, and maybe throw around some ideas. I also have a quad rotor, using just about the same things, I'm running an arduino mega because I plan to integrate heading and barometric pressure.

I'd like to get some help with software and trying out some autonomous flight.

Thank You

I'm eagerly waiting to hear from you :)
