Arduino distance meter with Ultrasonic Sensor (HC SR04) and Nokia 5110 LCD display

Measuring distance is so important in today’s world that things like driverless cars will be impossible without it, that description is probably enough to describe how important knowing the distance between two objects can be. For that reason, today we will be building a distance...
