RF Modules

[Shrikant]

Can someone please help me out with the decoding of data on the receiver side.

am using an arduino uno at the transmitting end as well as the receiving end..i wanna transmit 4 bits of data..! 

Thank you

Hi,

Which RF module are you using?

Hi Shrikant,

For transmitting data via RF module you need an encoder and decoder set to be connected to RF module receiver and transmitter, such that data pin of tranmitter (RF)is connected with encoder’s output pin and that of decoder’s input pin is connected to receiver‘s (RF) data pin. Here u need to use HT-12E n HT-12D encoder decoder set for 4-bit data tranmission. The data to be transmitted is sent to encoder input pins and transmitted data will  be received on decoder’s o/p pins.

hey. Thanks alot for the reply.

However, i’ve already used the encoder n decoder ics. The problem am facing is at the decoding of the recieved data(from the decoder ic to the muc/arduino board). When i checked it using the serial monitor, i was getting random values continuously n not the data that i transmitted.

 

Am using the 434MHz transmitter Reciever pairs locally available

It is better to try on LCD….

hey..i’ll surely try that..but any particular reason for it ??

Hi Shrikanth,

The serial monitor can display ascii characters only. If you need to display ‘1’ in the serial monitor you must receive the value ’49’.

Posting your code here will get you more helpful answers.

add your data with (data+0x30) or(data +48) in order to get your correct value.
