Telephone Ringer Lightshow

Sometimes an audible telephone ringer just isn't up to the task: Perhaps the phone is located in a noisy area, like a workshop, or a quiet area, like a library, or maybe the user is hearing-impaired. Whatever the reason, this project will help. Designed around the tiny Arduino Pro Mini, this device detects telephone ring signals and generates attention-grabbing patterns on an RGB LED light strip.
