  2 |    This is the code for controlling 4 appliances and 
  3 |    sending DHT11 sensor's data to Blynk App.
  4 | 
  5 |    After that, I made my own voice app using which, I
  6 |    can directly ask the status of appliances and value
  7 |    of Temeprature and Humidity directly to my Alexa
  8 |    smart speaker.
