Where does that error happen? Can you describe your exact problem in more detail?

Thank you for your patience!

This is on the Android Temperature Module project.  I have loaded the arduino sketch and the related app on my android.  When I try to connect to the Bluetooth module on the arduino I get the following message “Bad aruments to <  The oeration < cannot accept the argumkents:, [*empty-strubg*]m[5]”

What do you see in your Arduino IDE serial monitor? Can you copy and paste the full messages?

On the serial monitor the number -127.00 was repeated over and over again.

Your sensor isn’t working properly, because when it prints -127.00 temperature is an error value. Can you double-check the sensor wiring? Can you try with a different sensor (the sensor might be faulty)? 

OK I will work on the sensor soon.  Thanks for the quick response.

You’re welcome! Let me know your results.

I was only able to get the Thermometer project to work by rewiring the DS18B20 portion of the circuit.  The circuit in the provided pdf document showed the sensor pins 1 and 3 both going to ground.  Was this an error?

This is the wiring I used to correct the problem reported.
I was unable to insert images I have in a word document.
 
 

Hello Ernst, I’ll be trying to add files upload in the next update. In the meantime, I recommend using a link to Google Drive file, dropbox, imgur.com, or box.com (any file sharing service).
The DS18B20 can be configured in two modes (both are correct): https://randomnerdtutorials.com/guide-for-ds18b20-temperature-sensor-with-arduino/

Did you use option #1 from the schematics above to make it work for you?
