Alexa – Lampen ein – Meine Elektronik Projektinformationen

Hier zeige ich wie einfach es ist ein oder mehrere Lampen oder andere Geräte mit einem Amazon Echo Dot zu schalten.

Voraussetzungen:
Amazon Echo
Einen gültigen Amazon Account
WeMos mini mit ESP8266
Relay Karte
Steckboard Kabel 6 Stück
Steckboard

Hardware:

Original Software:
https://github.com/CharlesJGantt/LinkNode-R4-Controlled-By-Amazon-Alexa/tree/master

Schaltung:
Pin D0 -> IN1 (Lampe 1)
Pin D5 -> IN2 (Lampe 2)
Pin D6 -> IN3 (Lampe 3)
Pin D7 -> IN4 (Lampe 4)
5V -> Vcc (braun)
G -> GND (blau)
