I just want to convert the default projection of an Openlayers 3.9.0 from the default `EPSG:3857` to `EPSG:4326`.

So I edited a basic code like 

```
var layer = new ol.layer.Tile({
    source: new ol.source.OSM()
});

var center = [-1.812, 52.443];

var proj = new ol.proj.Projection({
        code: 'EPSG:4326',
        units: 'm'
});

var view = new ol.View({
    center: center,
    zoom: 6,
    projection:proj
});

var map = new ol.Map({
    loadTilesWhileAnimating: false,
    loadTilesWhileInteracting:false,
    target: 'map',
    layers: [layer],
    view: view

});

```

If center is like `var center = [-1.812, 52.443];` it does not go in the UK, as is should be, it goes in the center of the map.

If I do like `var center = new ol.geom.Point(-1.812, 52.443);` I see no map at all. What am I missing here?

Thanks
