MyReed-Switch Controlled by Particle Electron

// Reed-Switch with Particle Electron - works with v0.6.0 without Libaries
// Ingo Lohs, v1.0 v. 04.08.2017
// Projekt, um eine Eingangstür des Nachts zu überwachen
// Signalisierung erfolgt via IFTTT an Empfänger bei Trigger des Events
// v1.1 - Umstellung des REED_PIN_IN von Input zu Input_Pullup > so bleibt der Zustand erhalten - gab sonst Probleme mit IFTTT
//      - Streichung der Delays unter Aufnahme von lastmillis bei Auslagerung in die Funktion "readData()"
