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 ...

Arduino library for U8 series laser distance sensor. U8 series is an accurate LIDAR (ligth detection and ranging) sensor module with +/- 1 mm accuracy from JRT Meter Technology. This library support ...

[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 ...

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 ...

In one of our previous tutorials, we have shown you how you can interface LM35 Temperature Sensor with Arduino because it's cheap, easy to use, and requires minuscule power for stable operation. But ...

Abstract: TDS automatic data collection was designed based on a sensor and Arduino board using red laser beam communication. The sensor was calibrated by measuring 4 different water solutions using a ...

An impressive persistence of vision laser projector built using an Arduino and a hard drive case has been demonstrated by a DIY enthusiast. The device uses a circular array of rapidly spinning mirrors ...

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 ...
