This Arduino based IR reflectance sensor can be easily modified and adapted for various practical applications, including line-following robots and proximity or edge detection.

We’ve featured a few similar projects before, too; it’s all thanks to the fact that thermal sensors are getting cheaper and more accessible than ever!

To be fair, it does a wonderful job of controlling sensors, reading and logging data, and handling simple operations reliably. But the Arduino is more than just the Uno.
