1 - Conecte o módulo LDR à protoboard. 2 - Conecte o módulo LDR ao Arduino utilizando 3 jumpers: 3 - Conecte o pino GND do módulo LDR ao pino GND do Arduino. 4 - Conecte o pino VCC do módulo LDR ao ...

This is a simple project to control a laser security system with Arduino. The laser is controlled by an ATmega32 which enables the laser to blink at a certain rate. This laser is sensed by an LDR ...

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 ended up using a microcontroller and a piece ...

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 ...

Photoelectric sensors detect objects and surface changes using variations in optical properties. Each sensor includes a light emitter and a receiver, with most relying on infrared light. In optical ...

[Philip]’s Laser control Arduino shield. [Philip Nicovich] has been building laser sequencers over at the University of New South Wales. His platform is used to sequence laser excitation on his ...
