PICers - i'm looking round for ideas to build an IR modulator cct. did a quick google but mostly fopund IR receivers. I'm using a 16f84 to drive an IR led but i'll need to modulate it at 38kbps. i guess i could use a 555 to gate the LED on/off - any other ideas? thankz 4 advice best - Debbie :) http://personals.yahoo.com.au - Yahoo!
