Hi

I am doing some simple stuff with IR emitter and recievers. For now I am just triggering, not sending data...

I am using the Vishay TSOP4838 IR reciever. This accepts signals with a carrier frequency of 38 khz. My question is - How can I pulse (IR) leds at this specific frequency? I have been looking at the pwm stuff on the site but cant understand how to change the frequency... I may be being stupid as I am fairly new to the world of electronics....

Thanks

Netics
