Basically, the microcontroller-compatible motor speed sensor module described is a simple device that yields processed pulse trains when the visual path of its optical sensor is physically ... the ...

[Fearless Night]’s optical theremin project takes advantage ... instrument with software that can be modified using the Arduino IDE to take it places the original Theremin design could never ...

Here is a design concept for a cheap single point optical liquid sensor that can detect the presence or absence ... a logic-level alert signal in either a filled or empty state. An Arduino Uno ...

But entry-level CNC routers don’t often include a spindle tachometer, forcing the operator to basically guess at the speed. This DIY optical spindle ... be easy. The sensor hangs down just ...

Why not create your very own high-speed camera trigger using an Arduino, piezoelectric sensor (as a sound sensor), a DSLR camera, and an external flash. Watch the video after the break to see it ...

The next generation optical speed and length sensor ProSpeed LSV-2100 is designed to reliably perform even under harsh conditions and with up to 3 meters stand-off distances. ProSpeed is the reliable ...

The XS018 process supports pixel sizes up to 200µm x 200µm with high-speed ... optical sensing their applications demand. We are pleased to meet this need with our new XS018 CMOS image sensor ...
