    i am doing a project WIRELESS DEVICE CONTROL of appliances.
    please sir help me out i am able to turn on and off devices at the slave end using wires i.e i have connected tx and rx of microcontroller but i want to control the devices wirelessly so i have connected RF modules (ask 434) bought from visha electronics.
    now the problem is that teh modules r working fine when i give a 1khz square wave to transmitter and check at receving end its working fine. but when i give serial data to TX module from MICROCONTROLLER the receiver is not able to receive the signal i.e serial data i have tried at various baud rates. also at tranmitter on data pin a pulse from high to low is received when i press the switch .
