Arduino Coding help

Hi guys, I'm looking for some help. I saw this video

and I have the components necessary minus a few dials. Does anyone know how I could take that MPU 6050 accelerometer input and translate it to the servos so that when the car accelerates, the servos would wobble a little mimicking a real suspension? I've built the mechanical assembly and now I just need to code it. The goal is to get it to act just like in the video linked above. Any help would be great.

Thanks guys.

Geez that looks cool ... it would be good if that video had links to any existing source code, and we could take it from there.
... ah, that's an existing device that's not using Arduino: https://www.superscale2k20.com/ so I guess you're starting from scratch with the source code.
So you're using 4 servos? Have you figured out how those are going to be connected to the Arduino yet?

I came across a circuit development website, so I plugged in my components and this is what it came up with. Does this look correct at all?

I can only give feedback on some of the digital connections - I'm not sure if the other components on the board (capacitors etc) are correct.
Looks like the servo position will be driven via PWM. Based on this image (https://www.circuito.io/blog/arduino-uno-pinout/) I don't know if the first or third servo is connected to a pin that can drive PWM (first being left most in the diagram).
The wiring for the MPU 6050 looks right based on another Arduino project I've found based on a search.
I guess there are 2 next steps:
- see if you can read the output from the MPU 6050: print to a PC via the USB?
- see if you can control one servo, or if you really want, go for all 4!
What circuit development website did you use? I'd be interested to have a look ...

A couple of interesting links that can help:

MPU6050 Gyro Sensor Interfacing with Arduino

MPU6050 sensor consists a MEMS accelerometer, a MEMS gyro, and temperature sensor. This module is very accurate while converting analog values to digital because it has a 16bit analog to digital converter hardware for each channel. In this article we are going to interface this MPU6050 Gyroscope...

Controlling Multiple Servo Motors with Arduino

We are going to show you that how to control Multiple Servo Motors with Arduino. Connecting multiple Servo Motors with Arduino seems to be easy and but if we connect all the Servos to Arduino supply pins then they won’t work correctly because of lack of enough current to drive all the motors.

The second one seems to better correspond with where I would expect servos to be connected to the Arduino. Both links seem to have code samples.

Ok, ill take a look at them. For now, how would you set up the 4 servos with the mpu6050 and arduino?

(FYI, I have little to no coding experience whatsoever)
