How can I test the IR diode or the whole remote controller without an oscilloscope or any major test instrument?
I just want to know whether it generates IR.

If you just want to know wether the Remote handset transmits IR or not, you may use this simple circuit which works directly on the mains supply.DrWhoF said:How can I test the IR diode or the whole remote controller without an oscilloscope or any major test instrument?

Yes for an average hobbyist, i would recomend the same. But the said circuit is sold, enclosed in a cute plastic cabinet in every component vendor shop for the benefit of TV and other technicians. For Simple DC operated circuit, one may prefer the cicruit given below...CheersIanP said:I'm not sure how do you fill about mains voltages in such simple application, but I can tell you one thing: it is bloody dangerous ..
If you want to construct this circuit replace the H-voltage connection with a 9V battery, or any L-voltage power supply ..Rgds, IanP
