Pulsing/Throbbing Glow Effect on Sphere?

Hey, I’m looking for a method to implement a pulsing glow on an object (i.e. a sphere) for a powerup/collectible type prefab. I know barely anything about Unity and am on the path to learning more about it, so does anyone know how to achieve this? I’ve done some research but the only thing I’ve found that is relevant is using the Glow effect shader that is available in Unity PRO, but I haven’t heard any mention of being able to make it pulse or tween.

make a sphere and add a material with any color you want and in material make the shader as self illumine add a point light near to that sphere and and make the color of the light exactly as you have applied to the sphere and increase the intensity of the light as you wanted and tick the draw hallo in the spot light which you have used near to that sphere then you will get some pulsating effect
