The YL-70 line tracker sensor module kit includes another small sensor module, the YL-73, which contains an infrared light emitting diode and an infrared ... one-channel touch-free toggle switch using ...

This compact tracking sensor module not only can detect transitions from light to dark lines/rails but also objects ... Now to a simple even counter project using HW-006 module and Arduino Uno. This ...

Because his blinkenlight shield can be used as a light sensor, all that’s needed is a mirror and a pretty long line of sight. There’s a few problems with the setup though: with the Arduino ...

It’s contact-less, undetectable to the human ear, and it isn’t affected by smoke, dust, ambient light ... beam overlap and wired up to an Arduino Uno. One sensor’s emitter is blocked ...

The new TMD2755 module’s footprint of just 1.1mm x 3.25mm is some 40% smaller than that of the next smallest comparable 3-in-1 (IR emitter + IR detector + ambient light sensor) modules on the ...
