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 ...

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 ...

[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.

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 ...

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 ...

The Arduino Plug and Make Kit provides a 10-minute, cloud-based IoT solution that includes QWIIC and smartphone-based sensors, transducers, and actuators. Arduino’s new QWIIC-based UNO Plug and ...
