update your skills

                                      I ntroduction Hai everyone welcome friends this blog for you.. I upload arduino codings for you . Then you easily copy that and then upload in your arduino... REFERENCE:  youtube channel .. My important project is home automation.. If you have an great ideas about home automation plz comment in comment box... And also comment my drawbacks.. 

This is the codings for home automation program Here we control 4 relays ,water level induction ,thermal and humanity  , motion detection and it is send to could (adafruit io) and it also receive the codings using python program. the arduino program is below....... for reference visit the video.... my automation video (youtube video link)                              arduino program #include <dht.h> #define dht_apin A0 dht DHT; int data; int LED=13; int fan=5; int motor = 9; int light, waterup, waterdown, PIR, thermal,humidity; //output of pir pin2 and light sensor pin6 //waterup output A1 and waterdown A2 //thermal output A0 void setup() {    Serial.begin(9600);                               //initialize serial COM at 9600 baudrate   pinMode(LED, OUTPUT); //totally free pins are 3,4,7,8;   pinMode(12, OUTPUT);   pinMode(11, OUTPUT);   pinMode(10, OUTPUT);   pinMode(motor, OUTPUT);   pinMode(fan, OUTPUT);   pinMode(6, INPUT);   pinM
