Hi @sunty.apple,

Your code seems fine to me. Now check if your connection is correct.

  1. Connect the VCC pin of LM35 to 5V pin of the Bolt device.
  2. Connect the GND pin of LM35 to GND pin of the Bolt device.
  3. Connect the analog output pin of LM35 to A0 (analog input) pin of the Bolt device.

Also check if the wire is loose.

Do let me know in case you need further assistance.
