Laser ranging has many applications in production and life, such as ranging, positioning, obstacle avoidance, and so on. Time-of-Flight (ToF) ranging, as a type of laser ranging technology, is often ...

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 ...

Lasers are some of the coolest devices around. We can use them to cut things, create laser light shows, and also as a rangefinder.[Ignas] wrote in to tell us about [Berryjam’s] AMAZING write-up on ...

[Brian] started out with a clear and concise goal, “allow a regular human to associate an audible tone with a temperature from an infrared contactless thermometer.” With his latest project, the ESPeri ...

Abstract: We connected $\mathbf{p H}$ sensor and solar cell into Arduino Board to control data transmission via red laser communication or popular known as visible light communication (VLC). The ...
