I had some issues with the 433Mhz RF TX/RX..
Could not get anything across the VirtualWire library using the example Transmitter and Receiver sketch...
I m using some other brand of 433Mhz and found the pinout below:-
TX :
RX :
I hv the Arduino/Processing Graphing and confirm that the Transmitter is working... the high/low signals ( 1 & 0 ) output from the TX pin is also received on the antenna hole in the Transmitter..
On the receiver side, I'm a bit clueless on how to troubleshoot...
Got a lot of signal from the RX pin but the pattern does not match the TX and with some noise ( some half wave instead of square wave digital shape )
Could NOT get one matching message from the VirtualWire...
Tried all speed, from the default 200, 4800, 9600... nothing works..
Both running Arduino 328 with IDE 019..
Any idea how to Troubleshoot the Receiver ??
Thank you
Stanley
