Hi, I want to have an IR LED transmit a 38 kHz signal to. I want to be able to have the Arduino do it. This will then be detected from by a TSOP 1738 38 kHz IR receiver connected to the Arduino. That detection will then be will be used as a switch. Where once it is triggered another thing happens. This is the same as used on a robot in obstacle avoidance. My object will have the transmitter and receiver side by side and then when an object for example a hand passes in front of it and it detects something is there something else happens.
My question is can the Arduino send a 38 khz signal ot to the LED? I have done it with a Basic Stamp with the FREQOUT command in pbasic. Anything like that in Arduino?
