// this is a simple example that uses the easyMesh library
//
// 1. blinks led once for every node on the mesh
// 2. blink cycle repeats every BLINK_PERIOD
// 3. sends a silly message to every node on the mesh at a random time between 1 and 5 seconds
// 4. prints anything it receives to Serial.print
