2 channel Ir remote control Only 2 transistor

Flip Flop

touching any bass pin with a  transistor that transistor’s led is glowing and the other one is of.

this type of circuit are called flip flops circuit.

for receiving IR sense i used IR sensor 

there are 3 pins in an IR sensor which are positive negative and cathode output.

this cathode output is works on 38 hz

this is enough for this circuit 

connect this IR sensor’s output pin to a transistor’s base pin 

and i press any key of my remote and the transistor’s light turned on,

but unfortunately it is not turning off 

because there is no connection of negative sense on the second transistor’s base pin.

so i use another IR sensor for this transistor too. i know this is crazy 

but within this component it is a good idea,

now the light is turning on and off 

now it is working perfectly.

but here i faced a problem 

when the two sensors is getting sense in same time then they are working as crazy.

therefore you have to chose an angle to make it work perfectly
