Error to compile
-
Hi i'm trying to run the sketch code bellow in arduino IDE 1.8, but i'm receiving this error:
Monitor serial : ash: telnet: not found
https://docs.onion.io/omega2-arduino-dock-starter-kit/arduino-kit-reading-a-temp-sensor.html
Any idea?
exit status 1

@leo-moura Congratulations! You've flashed / uploaded a sketch successfully.
I think this error message brothers you:
Monitor serial : ash: telnet: not found
Onion's Arduino Dock 2 isn't able to communicate with Arduino IDE's Serial Monitor
by defaultdue to the HW concept.
You should use Omega2's CLI instead. Connect to it with ssh and type - for example - this command:
cat /dev/ttyS1

@György-Farkas worked in ssh terminal
But i have a doubt about the data read :
Seems wrong , why : 406.05 degrees C?
406.05 degrees C
762.90 degrees F
4.57 volts
407.03 degrees C
764.66 degrees F

@leo-moura Probably the analog pin A0 is not connected - it's floating.
Check the sensor. TMP36 should be connected - when facing the flat side of it (you can read the text):
the left pin to 5V, the middle pin to the analog pin A0, and the right pin to GND.
Though I think it's OK - you could check the program (and Arduino) too - without TMP36.
Connect the A0 pin to GND and you should see:
0.00 volts
-50.00 degrees C
-58.00 degrees FMake a resistive voltage divider: 5V -- 200 Ω -- 200 Ω -- 100 Ω -- GND.
Connect the A0 pin to the 100 Ω resistor and you should see (approximately):
1.00 volts
50.00 degrees C
122.00 degrees FGood luck!
