Topic: RF transmitter and receiver with NPN transistor (Read 825 times) previous topic - next topic


I have an RF transmitter(http://www.sparkfun.com/commerce/product_info.php?products_id=8945 and a receiver http://www.sparkfun.com/commerce/product_info.php?products_id=8948. I am trying to send a HIGH and LOW signal over them...the transmitter is hooked up to pin 11 on the Arduino and the receiver is connected to an npn transistor to let an led turn on(DATA out from receiver is connected to base of transistor.The problem is the LED is always "on" or is "blinking" and flashing out of control....any suggestions???
