How to make an IR toggle switch

Image
Hello, today I will show you how to make an IR toggle switch with Arduino and a Mosfet, it has far more detection range than capacitive touch device and easy to build. The circuit is easy to use and use minimal components to make a job done, now let's start
Components list:
R1 = 100 ohms resistor
R2 = 470 Kilo-ohms resistor
R3 = 10 Kilo-ohms resistor
R4 =1000 ohms or 1 kilo-ohms
IR1 = infrared led
IRR1 = infrared receiver
led = low forward voltage led, you can find it on any electronic part store
Tube1 =Shrink tubing
1 x irf9540n p-type Mosfet

If you have the components I list ready, it's time to upload this code to your Arduino UNO r3

 * Each time the input pin goes from LOW to HIGH (e.g. because of a push-button
 * press), the output pin is toggled from LOW to HIGH or HIGH to LOW.  There's
 * a minimum delay between toggles to debounce the circuit (i.e. to ignore
 * noise).
