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.

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 ...

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 ...

Showing that you can communicate between two Arduino development boards using ultrasonic ... the source code for the transmitter and receiver, we can see it’s about as basic as it gets.

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 ...
