Apart from the Arduino UNO, the circuit consists of two more primal ... For example, I used the output signal of the proximity sensor to trigger my old wireless doorbell thru an optocoupler after ...

You may be wondering why the Trigger and Echo pins in the module ... Stay tuned for that do it yourself project. Below is the Arduino Sketch used to test the JSN-SR04T ultrasonic distance sensor. This ...

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 ...

[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 ...
