This example demonstrates how to connect a laser distance sensor to an Arduino board using the I2C communication protocol.
Hardware Requirements:
- Laser distance sensor (e.g., LDJ series)
- Arduino board (e.g., Arduino Uno or Mega 2560)
- Breadboard and jumper wires
Connection Steps:
- Connect the sensor's power pins (VCC and GND) to the Arduino's 5V and GND pins.
- Connect the sensor's SCL (clock) and SDA (data) pins to the Arduino's corresponding I2C pins (typically A5 and A4, depending on the board).
- Ensure the sensor's operating voltage is compatible with the Arduino. Use a level shifter if necessary.
