When I was going through the Arduino Starter Kit projects, I noticed that I could combine projects 3:Love-O-Meter and project 11:Crystal Ball together and create a display that could read temperature sensor inputs. Few things to make note of:

  • Make sure potentiometer is connected!
  • There are a lot of wires, so make sure to follow the schematic exactly as written.
  • The tmp36 sensor Vout should be linked to A0 (analog pins).

EXPANDED TECHNICAL DETAILS

Analog Precision Temperature Monitoring

This project provides a real-time, high-contrast temperature dashboard using the TMP36 analog sensor.

  • Voltage-to-Celsius Calculation: The Arduino captures the analog voltage (0-1023) and applies the TMP36 transfer function: $Temp(C) = (Voltage - 0.5) imes 100$.
  • High-Visibility Display: Temperatures are rendered on a 16x2 character LCD. The firmware includes an "Average Sampling" routine that takes 10 readings per second to smooth out minor electrical fluctuations.

User Configurable

  • Fahrenheit/Celsius Toggle: Includes a simple button input to switch between metric and imperial units on-the-fly.
