People often ask, how to use Lidarlite 3 Laser Rangefinder?
Let’s find out!
How to Use Lidarlite 3 Laser Rangefinder?
The Lidarlite 3 is a handheld device that measures distances from 0.1m to 10m. It has a built-in rechargeable battery and uses LED light technology. The unit comes with a carrying case, charger, and user manual.
Features
This product is an electronic compass. It uses magnetic fields to determine the direction and is accurate within 2.5 centimeters when used outdoors. You can also use this device to navigate indoors or outdoors. It weighs less than two ounces. It updates every second. This rangefinder can also be used for navigation purposes.
This laser diode module is designed for use in medical applications. You should not attempt to repair this product yourself.

Documentation and Support
Operation Manual safety information declaration of conformity Arduino lidar-lite V3 GitHub spare / Extra lidar-lite V3 cables when space and weight requirements are tight, the lidar-l lite V3 soars.
It’s the ideal compact high-performance optical distant measurement sensor solution for drone robot or unmanned vehicle applications. Using a single chip signal processing solution along with minimal hardware, this highly configurable sensor can be used as the basic building block for applications where small size light weight low power consumption, and high performance are important factors.
This device is a reliable and powerful ranging and proximity detector. It is user configurable so you can adjust the distance and power output. It is suitable for drones, robots, and unmanned vehicles.
A compact, lightweight device that measures temperature and humidity. It communicates via I2C and uses PWM to control the fan speed. It requires a power supply and an external microcontroller.
Case
The LIDAR-LITE v3 has two tubes on the back. These tubes contain a laser transmitter and receiver. You must face them towards your target. The LIDAR-lite v3 also has an electrical port on the side. Connect this port to the included 6-pin connector to break out the pins for soldering.
On the back, there are four mounting holes that are designed for M3.5 screws.

Wires
This LIDAR-lite has 6 wires that can communicate with the sensor. The red wire powers the sensor. The orange wire enables the internal pull-up resistor. The yellow wire controls the PWM mode. The green wire is the clock signal. The blue wire is the data line. The black wire is ground.
The Lidar-Lite Accessory cable is terminated with a simple six-pin just at one end and a pigtail at the other end. The sensor needs to be connected to the computer using an accessory cable.
Power
Both models of LIDAR-Lites use about 5 volts of power. The v3 model uses more than the v3HP model. The v3HP model should be used if you need less power.
Hardware Assembly
The LIDAR-lite communicates using I2C.
A simple LED display using an ATtiny85 microcontroller. This project uses a single wire connection to communicate with the microcontroller. The output pin is connected directly to the ground. The input pin is connected to the positive terminal of the battery.
When the button is pressed, the microcontroller reads the state of the input pin and outputs a HIGH signal (5V) to turn on the LED. When the button is released, the microcontroller reads a LOW signal (0V) from the input pin and turns off the LED.
Resistors are good things, but sometimes we need to use them to stop our circuits from working properly. We also need to use resistors when building circuits that require more than one resistor. Resistors are used to make sure that currently doesn’t flow too fast or too slow. They are also used to limit voltage levels.

Software
The LIDAR-LITE library makes it easier to work with the LIDAR sensor. You can use the library to read data from the LIDAR sensor and display it on the screen.
Distance measurements are taken every 100 readings. A measurement without bias correction is taken at the beginning of each reading. Measurements with bias correction are taken after each reading.
Troubleshooting
Solder the wires to header pins before connecting them to the Arduino. Don’t use heat shrink because it could damage the headers.
A row of headers – break down to fit. 40 pins which can be cut to any shape. Used with custom PCB or general custom headers. We love heat shrink, and use it to reinforce connections and protect devices. Also, we use it for all sorts of handy projects. Use it for reinforcement, protection, and electrical insulation.
