Create dynamic widget for the sidebar home in Wordpress

I have only managed to create a widget but for the admin dashboard and I want it for the home

add_action('wp_dashboard_setup','dcms_agregar_widget');

//Agregar Widget
function dcms_agregar_widget(){
    wp_add_dashboard_widget('id_mi_widget','Mi Widget de Ejemplo','dcms_mostrar_widget');
}

//Mostrar Widget
function dcms_mostrar_widget(){
    echo "Hola desde mi nuevo Widget";
}
