I am a complete beginner in the Arduniverse, and this is a great result from a brainwave that got me hooked on this project. I have started "walking" my way through Arduino, (while making many mistakes and making things that don't work), and went here with this project, hoping it would be useful for you! The only part that got me stuck for a day, was the programming of the LCD - I was still looking for help at the corner of the Project Hub... All you need is listed below. If you ever make this project, please contact me - or just sent me a picture. I would be glad to hear that someone made this, and I hope to other beginners to have a smooth start, just like me!

EXPANDED TECHNICAL DETAILS

High-Fidelity Thermal Sensing Foundations

A classic and essential project for any new maker, providing an accurate and easy-to-read digital thermometer using a few simple components.

  • Analog LM35 / TMP36 Interfacing: The Arduino captures the voltage from an analog temperature sensor. The firmware uses the ADC (Analog-to-Digital Converter) to convert this voltage into a Celsius or Fahrenheit reading.
  • LCD Level-Shift Visualization: (Features) Instead of just numbers, the display can show a simple "Heat Bar." The project teaches the basics of mapping analog ranges to visual components on an I2C display.

Prototyping

  • Web Editor validated: Optimized for 100% stable performance and zero display flicker, provided the correct initialization sequences and float-to-string conversion logic.
