Hi,
I'm in need of ideas on how to go about this.
I need to modulate IR emitters at various frequencies (30Khz to 50Khz as is the norm, but not for remote control purposes).
I'm told I cannot use 555 timer given the cumbersome setup of resistors and the fluctuation of the voltage dividers with respect to temperature. Cannot also use any micro-processor either.
I do not need to encode any data either. Just need to emit a modulated IR signal.
I am novice in this field and would appreciate any help I can get.
