In this fun project an ultrasonic distance sensor is used to detect a “target” (i.e., a person, a cat, a burglar, etc.). The Arduino illuminates (blasts) the target using an inexpensive laser diode ...

If you’re interested in building your own laser sky effect generator, you’ll need a few key components: an Arduino Uno, a laser module, mirrors, motors to spin the mirrors, a photoresistor, an ...

The soil moisture sensor module , built around the LM393 comparator, gives an active-low (L) level output when the soil is dry (determined by a pre-setted threshold value). This digital output (wet ...

Laser Timer Ramp Last Updated: 7/27/18. Teaching Standards: This module allows you to develop a timing system, which utilizes the Arduino’s fast internal clock to provide an accurate timing system for ...

Instructables member Patrick Panikulam has created a versatile wireless Arduino pen plotter and laser ... a work area of 200 x 162 mm and using a 1000 mW laser module which is run using ...

LiDAR technology utilizes laser light to measure distance to objects and terrain. Many of these sensor systems, such as Quanergy's solid-state unit for self-driving cars , can cost upwards of US ...
