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

Building a maze-solving robot is an intresting way to get into the world of robotics and autonomous systems. Imagine creating ...

I recently did tests with the IR sensor of a broken dvd player. The frenquencies of the signals are below 44kHz, wich means you can use the microphone input of your computer and audacity to record ...

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 ...
