Smooth tilt accelerometer

Questions & Answers
1

Can someone please help me. I have a tilt function that takes the accelerometer input from a mobile device to rotate my player which works but the rotation is really shakey. I have been doing research and everyone is pretty much saying to use Lerp instead of Euler but every time I have tried I have been unsuccessful in converting the script. Can someone please help me with converting from Euler to Lerp or give me suggestions on a better way of achieving my desired outcome.

	public float speed = 1f;
	private Vector3 myRotation;
	public Transform particle;
	
	void Start() {
		myRotation = gameObject.transform.rotation.eulerAngles;

	}
	
	void Update() {

		//float GetComponent<ParticleSystem>().GetComponent<Rigidbody2D>().transform.position.x

			if (Input.acceleration.normalized.x > 0) {
				myRotation.z = Mathf.Clamp (myRotation.z - 1f, -60f, 45f);
				transform.rotation = Quaternion.Euler (myRotation);
			}
			if (Input.acceleration.normalized.x < 0) {
				myRotation.z = Mathf.Clamp (myRotation.z + 1, -60f, 45f);
				transform.rotation = Quaternion.Euler (myRotation);
			}
}

here is an a quick image I made up in paint to show what I want to happen.

Here’s my rotating code.
Also note that it is better to use a ATan2 between the 2 points of the vector you need the angle for.
This would depend on the orientation you’re working with.
Using ATan2 would give you an angle that would feel more steering-wheel-like.

float _rollAngle;

void Update()
{
    if (rollObject != null) 
    {
        var angle = Mathf.Atan2(Input.acceleration.x, Input.acceleration.y) * Mathf.Rad2Deg;
        _rollAngle = Mathf.LerpAngle(_rollAngle, angle, 10 * Time.deltaTime);
        
        rollObject.transform.localRotation = Quaternion.AngleAxis (_rollAngle, Vector3.up);
    }
}

The following answer worked for me:
