how to generate 38khz of frequency from arduino???


According to the arduino reference pages there's a function called "tone()".

No, I don't answer questions sent in private messages (but I do accept thank-you notes...)


i have tried that but a maximum of 20khz was generated!!

Should be able to come pretty close by setting up one of the timers to output a fixed frequency. Lots of info at:
MCP79411/12 RTC ... "One Million Ohms" ATtiny kit ... available at http://www.tindie.com/stores/JChristensen/
