I know I am late here, but this looks like a very cool project for my kid.I am assuming I can safely use SG90 Servos too?

Nice project, Can you please help if this can work with DHT 11 or DHT 22 sensors as I have all the parts including these sensors.

Hi from India Becky, I am amazed to see you so good with electronics and circuits.You are certainly a inspiration for our next gen.I flashed your code on a D1-Mini board, and it connected fine to my Wi-Fi but Echo Dot (v3) is unable to discover the device.Here's the serial output.----------------------------------FauxMo demo sketchAfter connection, ask Alexa/Echo to 'turn <my light> on' or 'off'[WIFI] Connecting to 4G-Tower ..........................[WIFI] STATION Mode, SSID: 4G-Tower, IP address: 192.168.1.45off----------------------------------I am able to ping that board from my Laptop but Alexa is not ready to discover it !!Anything I may be missing ??

don't know why the motor is making some noise continuously.even when its Idle at desired angle.

Thanks for the wonderful projectI am building this in a couple of day.2 questions, Can be Also use BMP180 sensor and post its reading too ?and I get error while compiling asArduino: 1.8.0 (Windows 7), Board: "Arduino/Genuino Uno"temp-thing:23: error: 'DHT' does not name a type DHT dht(DHTPIN, DHTTYPE);I'll be most probably hooking up my Arduino Nano instead of UNO.
