Hi,

I am opening a new thread for this one to divide the issues.
As explained in the thread Blinking LCD I get invalid output for the Bed and T1 sensors. I triple checked the board and even replaced the capacitor for the T1 output suspecting that the problem might lie there. However, the problem persists and what puzzles me most is that T0 returns perfect results.
If I measure voltage between the pins I get.

T1 = 5V
BED= 0.5V
T0 = 0.8V

Clearly some component is failing, but then, why should T1 work? Or would it be the Arduino that is messing things up?

Any ideas?

thanks and regards
Berthold

Are asking over and over again until you get the answer you like?
Dust already wrote it could be a faulty AD-converter, since you switched the thermistors and they seem to work ( cold solder or broken thermistor legs checked?? )

Go back to a bare mega and test out the pins A13, A14 and A15

use this basic tutorial [www.arduino.cc]

All you need is to change the pin used in the code (and wire it to that pin)

(you do need to open the serial monitor to see the output)

Thanks!!
I had checked A13-15 and the voltage is as I wrote above. I have ordered a new Arduino now to see whether that fixes it.
Thanks again for the help!
