Color sensing (as well as detecting empty spaces) settled on IR-based sensors commonly used in line-following robots. ... arduino, dispenser, ir sensor, label, NEMA-17, stepper motor, sticker.

Some readers may recall building a line-following robot during their school days. Involving some IR LEDs, perhaps a bit of LEGO, and plenty of trial-and-error, it was fun on a tiny scale. Now imagi… ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I. ... 0 comments on “ Arduino IR Proximity ...

In the second phase, the logic operates two drive motors (left and right) as per the informed track status. The infrared sensor card contains infrared light emitting diodes and infrared photodiodes.
