The sensor uses a laser diode and a photodiode to detect and count particles, while a fan moves air through the system.

In this project, we create a joystick-controlled laser by connecting two servos to a joystick and using this setup as a pan-and-tilt controller for a laser pointer.

In this Arduino project, I show you how to build a simple servo laser tower controlled from a smartphone app called Blynk. This is ideal for making a toy for your cat or dog. #ArduinoProject # ...
