I was attracted to the idea of having a wireless hum/temp sensor and so I built this. I prototyped it on a breadboard, and I also soldered it on a PCB. I extended the antenna with a 8.3 cm wire.

But I can't get it to work stable. Sometimes it works for many hours and sometimes only for one hour. And then it just hangs. A reset of the at85 sometimes helps, but most of the times I need to power it off and on again.

I need it to work reliably for several weeks. Any suggestions ?

Have you got any suggestions?
Did you get it to work stable?

Or have you abandoned the project?

I see that I have post my question in the wrong forum.
Should have been in Hardware i.s.o. General discussion. (may be it doesn't make any difference)
This is the link: http://forum.mysensors.org/topic/1327/how-to-read-from-atmega328p-with-raspberry-pi

Connected via SPI (MOSI, MISO,.....etc)

I have compiled and flashed following program to the atmega328P (connected to a raspberry pi). This program reads a voltage on pin. A0

============================Begin program================================
const int analogInPin = A0;

float sensorValue = 0;

void setup(){
Serial.begin(9600);
}

void loop() {
sensorValue = analogRead(analogInPin);

Serial.print(¨Voltage Output = ");
Serial.print(sensorValue*5/1023);
Serial.println(" ");

delay(100);

}
===============================End program================================

I only use the command line in the raspberry pi. (no GUI)

When I've flashed the program I get the command prompt back.
Q: How do I read the values of the program in the atmega328p back in my raspberry pi?
