Building an Arduino speed detector using IR technology to measure the speed of a moving object is much more cost-effective, ...

Whether you're a student, hobbyist, or robotics enthusiast, this maze-solving robot project will help you understand the ...

The sensor is really just an infrared photodiode inside of a tube. The diode is connected to an analog input pin on an Arduino. The sensor can be pointed at an object, and the Arduino can sense ...

Color sensing (as well as detecting empty spaces) settled on IR-based sensors commonly used in line-following robots. You can watch the clock in action in the video embedded below just under the ...
