Interfacing VL6180 ToF Range Finder Sensor with Arduino for Distance Measurement TOF or Time of flight is a commonly used method to measure the distance of distant objects by various distance measurement sensor like ultrasonic sensor. The measurement of the time taken by a particle, wave or an object to travel a distance through a medium is referred to as Time-of-flight (TOF). This measurement can then be used to calculate the velocity or… |

Digital Taxi Fare Meter using Arduino Today digital meters are replacing analog meters in every sector whether its electricity meter or taxi fare meter. The main reason for that is analog meters have mechanical parts that tend to wear when used for long time and they are not as accurate as digital Meters. A good example for this is analog speedometer and odometer that is used in old… |
