The problem with mobile phones is that if you need lights, you’ve usually got two options. The first is to simply deal with the underpowered, far-too-close-to-the-lens built in LED. Unless you’re using in the front camera, in which case that’s usually not an option. The second is to lug around all the usual LED lighting gear you’d use with regular cameras. In which case, you probably might as well just use a regular camera.
The folks over at Adafruit, though, have come up with a great project to help solve this. A 3D printed smartphone case with a built in LED ringlight. Not only does it wrap the light around your lens instead of being right next to it, but it also offers a fair bit more power. That it’s controlled by an Arduino also means that you can reconfigure the lights to give some neat effects.
