can you also help me to modify your code for change frequency in "any" in the range specified ?
Look at the code:-
OCR2A = 51; // defines the frequency 51 = 38.4 KHz, 54 = 36.2 KHz, 58 = 34 KHz, 62 = 32 KHz
OCR2B = 26; // defines the duty cycle - Half the OCR2A value for 50%
Just poke different numbers into OCR2A and OCR2B to change the frequency.
