Imagine you're lying in your bed, it's cold and you're too lazy to get up from his bed to go turn on the light of your room. Then the same bed, you pick up the remote control for your TV and connect the lamp from your room and also off with the same control. Not a good design and interesting?
This is my project! Turn on and off the lamp in his room so many appliances in your home. The project essay around the photo down there ...

Step 1: Parts
1 CI 4017
1 Transistor BC 558
1 Transistor BC 548
1 Relay 5V 100 mA
1 Diode 1N4007
1 red LED
1 green LED
1 Capacitor 100uF 16 V electrolytic
2 resistors 1k - 1 / 8 W
2 resistors 330 to 1 / 8 W
1 resistor 100k - 1 / 8 W
1 Resistor 100 - 1 / 8 W
1 resistor 220k - 1 / 8 W
Step 2: Schematic, Adjustments, the PCB and Finish
The PCB is easy to make, and if you want to use the sensor TSOP 1738, you must modify the paths in the sensor. The board, which has a rectangle, over there is a place to cut, a tearing of the plate to make a network isolation and high current circuit, so to avoid interference.
Sorry, but I don't have pictures of assembly.
After you build your circuit, test and deploy it wherever you want. The circuit works with any remote control (often within the 38Khz). I hope everything goes right in your assembly. Until next. bye!
