I2C: Time- of-Flight Distance Sensor

I use Pololu's VL53L0X for this Lab.

Pololu - VL53L0X Time-of-Flight Distance Sensor Carrier with Voltage Regulator, 200cm Max

https://github.com/pololu/vl53l0x-arduino

On Arduino Nano, A4 pin is for SDA, and A5 pin is for SCL.

I use the code from Pololu's VL53L0X. The code for basic continuous range measurement shows below:

#include <Wire.h>
#include <VL53L0X.h>

VL53L0X sensor;

void setup() {
  Serial.begin(9600);
  Wire.begin();
  sensor.setTimeout(500);
  if (!sensor.init())
  {
    Serial.println("Failed to detect and initialize sensor!");
    while (1) {}.   // Is while(1) the same as while(true)?
  }

  sensor.startContinuous();
}

void loop() {
   Serial.println(sensor.readRangeContinuousMillimeters());
   //delay(10);
  if (sensor.timeoutOccurred()) { 
    Serial.print(" TIMEOUT"); 
    }
  //Serial.println();
}

Readings from Long Range mode

• Time-of-Flight Distance Sensor returns distance in millimeters which is pretty accurate and realiable.
• It works well when distance is less than 1m in normal mode. The library also includes LONG_RANGE, HIGH_SPEED, HIGH_ACCURACY modes. In the LONG_RANGE mode, it can sense up to 2.2m. If out of range, it returns "8190".

I2C: OLED Screen Display

I use Adafruit SSD 1306 for this lab, links below are its library and graphics tutorial:

Adafruit GFX Graphics Library

Basic display methods

display.print(); //display text

display.write(); //display ASCII

for ( int i = 0; i < 10; i++) {
  display.drawRect(i*6, i*3, SCREEN_WIDTH - 2 -i*12, SCREEN_HEIGHT-2 -i*6, WHITE);
 } //display Rect
