remote control home automation part 2

 hello guys my self Pankaj and welcome bake to Electronics Creator blog.

 In previous video we was learn  how to make remote control home automation, but in that video I was control only lights but in room we need to control also fan, and in room also we need to control all appliances by remotely as well as manually.

so for that I am making this video.

components list

1.  Arduino Nano 
2. 8CH touch sensor
3. bt136 triac  #3
4. Moc3021  #3
5. 2 terminal block  (conector) #4
6. optpcopler #1
7. 1N40007 diode #4
8. Rersistors 100k (#2) , 10k (#1), 2.2k(#1),  220ohm (#6).
9. 100nf 250V (box type) capacitor (#1)
10. TSOP 1838 IR sensor
11. dc female jack
    
12. connecting wires

you can buy this all components from quartzcomponents.com    or robu.in

this two are very trusteble sites to buy electronics components......

please follow the following circuit diagram to complite your pcb 

Note :  please make sure all the loads are connected in series with circuit  

you can download all the data from here  

dowonload the zip file you can get all arduino libraries circuit digram, and program......

you can also copy program here......
