Help! Need some help with Multiwii Issue

#1
Heyo, I'm completely new to building anything in my life and I just recently started to work on the drone. So, I got the basic quad-cop setup using arduino nano as the flight controller, but I got into some issue when I got to multiwii.

As for the wiring setup, I basically followed the schematic on this website (pwm). http://www.electronoobs.com/eng_robotica_tut5_3.php

In my current state, I got a basic setup of arduino nano and MPU-6050 for the gyro, and I'm able to read the info from the gyro and most of the receiver's data... but here's the issue:
1. somehow, arduino isn't reading the roll signal (pin D4) from the receiver (the receiver is properly getting the info from the transmitter, and I can see that it's sending because when I connect the roll output from the receiver to the tilt input of the multiwii, it reads it properly)
2. Multiwii DOES work when I connect it through usb... but it just freezes when I try and connect it to the battery
3. When I just connect it though the battery, it does light up... but it doesn't respond to anything... Even if I try and arm the damb thing. I did try arming it using Aux switch on the trasmitter controller, but no luck on that

But yeah... I need some help with this issue... Thank you.

As for the config setup, this is it:
The only thing I changed is uncomment QuadX and nanowii
Code:

#define CONFIG_H_

/* this file consists of several sections

* to create a working combination you must at least make your choices in section 1.

* 1 - BASIC SETUP - you must select an option in every block.

*      this assumes you have 4 channels connected to your board with standard ESCs and servos.

* 2 - COPTER TYPE SPECIFIC OPTIONS - you likely want to check for options for your copter type

* 3 - RC SYSTEM SETUP

* 4 - ALTERNATE CPUs & BOARDS - if you have

* 5 - ALTERNATE SETUP - select alternate RX (SBUS, PPM, etc.), alternate ESC-range, etc. here

* 6 - OPTIONAL FEATURES - enable nice to have features here (FlightModes, LCD, telemetry, battery monitor etc.)

* 7 - TUNING & DEVELOPER - if you know what you are doing; you have been warned

*     - (ESCs calibration, Dynamic Motor/Prop Balancing, Diagnostics,Memory savings.....)

* 8 - DEPRECATED - these features will be removed in some future release

Kicking it old school... Like really old school. I'd recommend getting a modern flight controller and running Betaflight, that's the easy solution. If you're set on this path, you may need to look elsewhere for help... I've never seen multiwii discussed here ;)
 
#4
The thing is, I had a modern flight controller and I kinda blew the voltage regulator. That's why I decided to use arduino cause I didn't want to wait another 1 month to ship that thing from China... oh well, I'll look for more options. If it doesn't work, welp I guess that's the only other option.

Thx for the suggestion. Also, I just found this out recently, but it DOES still work when it's connected to the battery. It's when the battery AND transmitter is on, multiwii just stop working LMAO
