They're not just for Arduinos... these are ordinary LED's. I used these to build a tally light system for a professional video camera. The LED's are bright, large and easy to see, with good diffusion across the surface. Use Ohm's Law to figure out the resistor value to use with a given voltage. I had some extras... I'll have to figure out something cool to do with them.
