Using Arduinos along with C and PHP coding, we created a system of sending distress signals of sort to different devices. When the distress signal is sent from one device, using a switch (on the Arduino board), the other devices detect the signal and switch on an LED light on the Arduino boards. The distance/range between devices is not limited as long as all of them are connected from wifi. This is because the data (signal) is being pulled from the internet/ OSU Webspace.
