text: hi,
  im kinda new to arduino and i was wondering if there might be any examples of a relay being used with
  a tof/VL53L0X sensor that a beginner my learn from? or maybe some reading material?
  thank you
  hi,
  A sensor and a relay never connects.
  sorry i guess i should express myself a bit better. basically id like to use a vl53l0x sensor control a relay thru a nano.
  basically i would like to be able to measure a distance and have the nano turn the relay on in a fixed range.
  ive been searching the forum and the internet for a starting point (lets say a tutorial or a library) and i get plenty of examples in setting up the sensor with a slightly advanced descriptions. i was wondering if someone might have some resourses for a simple man?
  Split the project in 2 parts. The first part could be "nano and distance". Explore the stuff You find there.
  The next step would be "nano and relay".
  Never put the hole lot of devices in a sack. Shaking the sack is not the way to get the lot working.
  How do You think mankind managed to land on the moon 1968? Surely they tested and verified every little part of the system before integrating them into the Apollo spacecraft.
  There's no easier way for Your resonable project.
  Can you get a range from the sensor and send the range to serial monitor using one of the library examples?
  What relay do you have? Is it a module with a transistor driver? A bare relay can't be driven from an Arduino output. You may need a separate supply for the relay coil.
  What Arduino board are you using?
  Here is example code to turn on a relay (simulated with the built in LED) when the range is under 100mm. I used the VL530X library by Pololu from the library manager.
  #include <Wire.h> #include <VL53L0X.h> VL53L0X sensor; const byte ledPin = 13; //#define LONG_RANGE //#define HIGH_SPEED #define HIGH_ACCURACY int distance = 0; void setup() { Serial.begin(9600); Wire.begin(); pinMode(ledPin, OUTPUT); digitalWrite(ledPin, LOW); sensor.setTimeout(500); if (!sensor.init()) { Serial.println("Failed to detect and initialize sensor!"); while (1) {} } #if defined LONG_RANGE // lower the return signal rate limit (default is 0.25 MCPS) sensor.setSignalRateLimit(0.1); // increase laser pulse periods (defaults are 14 and 10 PCLKs) sensor.setVcselPulsePeriod(VL53L0X::VcselPeriodPreRange, 18); sensor.setVcselPulsePeriod(VL53L0X::VcselPeriodFinalRange, 14); #endif #if defined HIGH_SPEED // reduce timing budget to 20 ms (default is about 33 ms) sensor.setMeasurementTimingBudget(20000); #elif defined HIGH_ACCURACY // change timing budget sensor.setMeasurementTimingBudget(50000); //Serial.print(sensor.getSignalRateLimit()); #endif } void loop() { distance = sensor.readRangeSingleMillimeters(); Serial.print("distance = "); Serial.println(distance); if (distance < 100) { Serial.println("close"); digitalWrite(ledPin, HIGH); } else { Serial.println("far"); digitalWrite(ledPin, LOW); } }
  Thank you. I shall venture thru those suggestions.
