Dear all,
I look forwad for your help on this.
I have tried using a 555 T imer IC to generate 38 Khz pulses to drive an Ir led. But the problem is that the TSOP 1838 receiver IC is not responding to the pulses. I made sure that 38 Khz pulses are being delivered and a LED connected to the Output of receiver IC flickrs when I use a TV remote.
I couldn't figure out what might be problem? I kind of think that the receiver IC is neglecting the 38Khz pulses from 555 as they are continuous? But I don't know what might be the solution??
