This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module ... The set-up process is very simple, and best understood by referring the wiring diagram.

Shifting to the new waterproof ultrasonic sensor is not a big deal, since it’s pretty easy to modify some example codes to use it. The quick road test, oh it’s a simple approach to display the ...

You simply connect your components to the board, use ... The code includes two Arduino libraries: one for the servo and another for the ultrasonic sensors. The main code is a simple 14-line ...

A simple way ... which one you are using so you can write the code accordingly. PIR Pin “out” connects to Arduino Digital 2 Here is the Arduino code for the Parallax sensor int motion_1 ...
