4 channel remote switch

Hi ! friends it took me very long to complete this video because it was not a simple task to make such project with out micro controller but i used a simple chip 4017 and some actually a lot of other component such as transistors capacitors led and many more. the whole recording of this project was 4 hour long so i decided to fast forward it . with this circuit you can turn on and off 4 devices such as tv fan lamp or any thing you want you can turn on and off all 4 devices individually .i have put a lot of effort into this project please appreciate my work and don't forget to like share and subscribe

components needed :

1- 1 x 4017 ic

2- 1 x tsop1838 ir receiver

3- 10 x 100uF electrolytic capacitor

4- 20x bc547 transistors

5- 9 x bv557 transistor

6- 24x 1k resistors

7- 37x 10k resistor

8- 8 x 47k resistor

9- 4 x 12v relays

10- 4x 1n4007 diodes

11- 4x red leds

12- 4x yellow leds

13- 4x green leds

14- 4x 10uF electrolytic capacitor

15- 1x 100R resistor

16- 1x 7805 regulator ic

17- 4x 3 pin terminal blocks

18- 2x 0.1uf (104) non polar capacitors

19 -vero board

20- jumper wires
