Показать описание
In this video I show how to control a RGB Led Strip of 12 volts using ESP8266 (Wemos D1 R1) or ESP32 or Arduino with Google Assistant (voice commands) and Google Home (touch control app)

This video requires a cloud application that I explain in details how to setup in the two videos below. It shows how to set up a Java Cloud Application (based on a Sample Java end-to-end for Smart-Home connection) that interfaces with Google Smart-Home and Home Assistant and forwards the Actions Commands from Google to smart devices using MQTT (MQTT interface implemented by myself).

ESP8266/Wemos code on github for Led Strip:

Arduino Uno code with Ethernet Shield:

Reference that shows how to connect the ESP8266 output PWM pin of 3.3 Volt level to PWM of 5 Volts level using a BUS Transceiver SN74HTC245 or SN74HTC125, see datasheet for more details
This conversion from PWM 3.3 Volts to 5 Volts DC is required for Data input of LED Strip of 12 Volts to work properly.
