Simple Home Automation

Hi
This is the simplest home automation using HC-05 Bluetooth module.

parts you need...

             components                                                                                  buy link

  • Arduino Uno (any arduino works)                                https://amzn.to/2MUYONt
  • Bluetooth module                                                          https://amzn.to/2AyfN5t
  • Relay module                                                                 
  • Zero PCB
  • 1K resistors
  • 2K resistor
  • 817 optocouplers 

circuit diagram 



here is how to connect any load or appliances with relay

here is the link for code


here is the link for Android app.

thank you for watching

Binary Clock

Hello friends..... here is how you can read binary clock ... here you can see 1,2,4,8 assigned for column. in the picture you can see in HH section first column first led is on so it is one,second column all led is off so 0 SO HERE HOUR IS 10. Now in MM section two led is on so add the assigned numbers. in picture add (1+2=3) and add(1+2+4=7) SO MINUTE IS 37. Then second (SS)  is 49. what you need....                     components                                                                           buy link  Arduino pro mini (you can use any arduino)                              https://amzn.to/2X7O8Qh ftdi programmer                                                                          https://amzn.to/2Tea5vJ   ds1302 rtc module                                                                        https://amzn.to/365RF5D leds                                                                                              https://amzn.to/3fZggNM zero pcb spa
