Arduino distance meter with Ultrasonic Sensor (HC SR04) and Nokia 5110 LCD display
https://www.electronics-lab.com/arduino-distance-meter-ultrasonic-sensor-hc-sr04-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 meter using the Arduino and the HC-SR04 ultrasonic sensor. The […]
How to Set Up an Ultrasonic Range Finder on an Arduino
https://www.electronics-lab.com/set-ultrasonic-range-finder-arduino/
circuitbasics.com has a new tutorial on how to measure distance using Arduino and an ultrasonic sensor. Ultrasonic range finders are fun little modules that measure distance. You can use them to find the precise distance to an object, or also just to detect when something is within range of the sensor (like a motion detector). Ultrasonic […]
Arduino radar using sound waves
https://www.electronics-lab.com/arduino-radar-using-sound-waves/
A radar system uses high frequency radio waves for object detection. A high-power RF pulse is transmitted into space and its echo reflected off from an obstacle is recorded. By computing the time elapsed between the transmitted and reflected pulses, and knowing that the electromagnetic wave propagates at a constant speed of light, the radar […]

HC-SR04 Ping Sensor Hardware Mod
https://www.electronics-lab.com/hc-sr04-ping-sensor-hardware-mod/
by cascologix.com: HC-SR04 ultrasonic sensor modules, also commonly called ping sensors, are practically a dime a dozen, with many Asia online retailers selling them in the $2 to $3 dollar range each. While possibly not intended for an end solution or product, these sensors offer a more affordable option for prototyping and application development compared […]
