i m tryin 2 make a remote that vl work an air conditioner
So my qustn is what should b the frequency of the ir led???
The IR carrier signal is usually 35 to 40 KHz but that frequency isn't very critical.
Will the circuit shown below do the receiving and show its output in the serial monitor to get the exact timings?
I tried connecting to the oscilloscope with this circuit but its not working
