On a sketch, for using SoftwareSerial (now Radiohead?), I found these lines:
const char *msg = "hello"; uint8_t buf[VW_MAX_MESSAGE_LEN]; uint8_t buflen = VW_MAX_MESSAGE_LEN;
These send the string "hello" over a transmitter to a receiver.
But... I want more. I want to sent, let's say, a number, a "counting" number every single second. Or other data over that transmitter.
Anyone an idea how I have to change that code?
