This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection. ... If everything goes right,you should see the ...

Buy arduino, buy sound shield, buy distance sensor shield, plug into each other, burn example code, stuff components inside box. Not only is this not a hack but he might as well have just bought a ...

The sensor shown here is essentially two plates mounted side-by-side, attached to an Arduino Nano using the Capacitor library which uses just two pins, one digital and one analog.

Krejci’s tutorial video guides viewers on how to construct an infrared camera using an Arduino UNO, an infrared sensor AMG8833, and an 8×8 RGB LED display from SunFounder.

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. ... Here is the diagram of my Arduino infrared close proximity sensor ...
