Hello,

The IR recievers can be frequency dependend.
You will have to find out on wich frequency you IR reciever is working.
I have found a datasheet for the tsop1738 but not for the other one.

One thing I noticed is that there is no current limiting resistor in the transmittor part.



This can mean that the leds are burnt and you will not recieve any signal.

Greetings,
Bertus
