Simple IR Remote Switch 4017IC & LM555
PART NO. 2223531
Built on a breadboard or can be soldered onto a PCB, this circuit contains a 555 timer and 4017 IC for easily switching on or off
projects/triggering projects using almost any IR remote (the one in the picture is a camera IR remote). The 555 is in mono-stable mode,
filtering out the pulses from the IR receiver coming from the IR trigger remote, then feeding a pulse into the 4017 clock input to switch
the output high from pin 2 & 3 every time the 555 sends a pulse.
Using this information, this circuit can be adapted by moving 1 wire (removing the wire that connects pin 4 to reset) to make a 10 pin
switching output, this cycles through the 4017 IC's outputs with every pulse from the 555)
You could also connect a transistor and relay together on the high output where the led would be to create a higher current switch for
turning on/off projects.
FYI: Once the circuit has power connected over ~6.5V the output of the 4017 will flick between the on/off positions because the photo-
transistor is rated at 5V, this is why a 5V regulator is included in the circuit.
Time Required: 30 minutes depending on experience
Experience Level: Intermediate
Required tools and parts:
-Wire
-IR remote control from a TV, camera, stereo, or other electronic device (will work with ranges around standard 940nm wavelength)
-9V battery
-If not building breadboard version, which is included, soldering tools and PCB

- Page 2 "optional" because the LEDs I used were rated for higher voltages, the green-red provided are around 2.3V. When building the circuit, your red led should attach to pin 3 on the 4017IC as that is the '0' output or the line that represents the circuit being off.
- Page 3 -Check that your voltage regulator is not backwards. The voltage regulator should have the flat side facing away from you. -Make sure your LEDs are the correct orientation, longer lead is usually positive or the large metal piece how inside the led casing is negative or the flat spot on the casing is negative -Check orientation of capacitor -Check for broken wires, connections, and corrector power connections...
