So, the target is 2.55 meters away (note that the speed of sound varies with temperature ... oh it’s a simple approach to display the distance measurements on the Arduino Serial Monitor. I will use ...

Inside [Klaus]’ device is an Arduino Uno, an HC-SR04 ultrasonic distance sensor, and an Adafruit Wave Shield. Originally, this parking/distance sensor used a small TFT to display the distance to ...

If your car doesn't have that feature, DIY blog Mad Science has put together a tutorial to roll your own sensor ... Arduino, a buzzer, and just a few wires. The sonic range finder emits a sound ...

[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors.

Likely applications are button designs and proximity sensing. The kit’s board also includes ... The kit works as a stand-alone unit and as an Arduino-compatible shield. It can be used to add a ...

While this may sound complicated, the software is actually beginner-friendly. It involves using two programs: Arduino ... correct distance before pressing the resistor, allowing the sensor to ...
