The pictures are good, although a little difficult to tell exactly what is what. I'll assume the wiring is all correct.
OK i'm pulling my brain out using LowPowerLab no.... not get me wrong, this is working ..... the examples
when i send data .... the receive led blinks randomly in stead to fade .... how i send the pot value
I'm not quite sure what this means? You didn't say which sketch you're using. Does the Led blink in response to the transmitted signal, or just goes randomly?
1. do the Send and Receive examples in the lowpower library work? That's the first thing to do.
2. once they work, then you can try the LED_Control_Gateway and LED_Control_node sketches.
These will allow you to send LED on/off/blink commands to the remote node. The pulse
command doesn't seem to work well, however, from what I can tell.
3. you will have to modify these sketches to send analog values and pot data. It's very simple.
If you look in the LED_Control_Gateway sketch, you'll see the following lines,
void sendMessage()
{
sprintf(sendBuf, "%c:%c", mode, theSpeed);
radio.Send(nodeId, sendBuf, 3, REQUESTACK);
....4. all you have to do is put your analog value into the sprintf() function, and it gets converted
to an ASCII text message and sent. So write something like
sprintf(sendBuf, "pot value=%04d", analogRead(A0) );
int len = strlen(sendBuf);
radio.Send(nodeId, sendBuf, len, REQUESTACK);
.......5. then on the LED_Control_node side, these lines in the existing sketch will display the message that was sent,
if (radio.CRCPass())
{
Serial.print('['); Serial.print(radio.GetSender(), DEC); Serial.print("] ");
for (byte i = 0; i < *radio.DataLen; i++)
Serial.print((char)radio.Data[i]);
