Social Distancing Monitor, Arduino NANO and Neopixel Ring

We realized already several projects for Social Distancing with LCD and OLEDs ===> https://gustmees.wordpress.com/?s=social+distancing and this time WE will use a Neopixel Ring who changes the color from green to orange and then to red depending on how close WE come to the 2 metres.

WE will have a look on the video who inspired me and where you will find more information:

 


Connecting the HC-SR04 Ultrasonic Sensor:

 

Connections to the Arduino NANO:

Vcc+ gets connected to + 5V

GND to GND

ECHO gets connected to PIN 2

TRIGGER gets connected to PIN 3

.


Connecting the NEOPIXEL Ring:

THE code

Please find below the code which I used in .doc format::

Copy and paste it into the Arduino IDE and have fun 😉

Social Distancing Monitor, Arduino NANO and I2C OLED Display

In times of the Coronavirus-Crisis (Covid_19), it might be GOOD to respect the 2 meters distance to avoid getting infected!!! But not everybody can estimate distances, nor are ALL persons respecting the 2 meters rule!!! So came the idea to build an easy to realize gadget, which measures the distance when the 2 meters are not respected.

First of all, like usual, I was searching the internet to find out if there isn’t already such a project around. And YES, there is one; I found a tutorial with an Arduino UNO with provided code as well. Please check below:

In a previous tutorial WE were already using a “Social Distancing Monitor with Alarm, Arduino NANO and I2C LCD1602 Display“, check below please for revision:


Connecting the HC-SR04 Ultrasonic Sensor:

 

Connections to the Arduino NANO:

Vcc+ gets connected to + 5V

GND to GND

ECHO gets connected to PIN 10

TRIGGER gets connected to PIN 9

All you need NOW is to put everything into a case… Have fun and stay safe!!

Social Distancing Monitor with Alarm, Arduino NANO and I2C LCD1602 Display

In times of the Coronavirus-Crisis (Covid_19), it might be GOOD to respect the 2 meters distance to avoid getting infected!!! But not everybody can estimate distances, nor are ALL persons respecting the 2 meters rule!!! So came the idea to build an easy to realize gadget, which measures the distance and gives an alarm when the 2 meters are not respected.

First of all, like usual, I was searching the internet to find out if there isn’t already such a project around. And YES, there is one; I found a tutorial with an Arduino MEGA and a LCD1602 ISP with provided code as well. Please check below:

 

This tutorial gave me the idea to start. Instead an Arduino MEGA, I used an Arduino NANO; and instead of an LCD1602 ISP, I used an LCD1602 I2C.

Thus meaning: it needs a bit to adjust the code in the sketch in the above mentioned tutorial and it’s LESS cabling, wiring needed to connect the I2C LCD1602 display.

WE played around already with I2C LCD1602 in my tutorial below, please check:

SO, here we go for the wiring… Below the wiring for the I2C LCD1602 with the Arduino NANO

:

I2C LCD1602 PINOUT-Arduino NANO

.

LCD-I2C-PINOUT-ARDUINO


Connecting the HC-SR04 Ultrasonic Sensor:

 

Connections to the Arduino NANO:

Vcc+ gets connected to + 5V

GND to GND

ECHO gets connected to PIN 10

TRIGGER gets connected to PIN 9


Connecting the Buzzer for the acoustic Alarm:

 

The + sign of the Buzzer gets connected to PIN 8 of the Arduino NANO and the other pin to GND!

Below you see the prototype with wiring.

.


The code

Here below see a preview of the Code:

The complete Code could get downloaded in “.doc” format below.

Download and open the document, copy it and bring it in a NEW Sketch of the Arduino IDE. Upload it to the Arduino Nano and have fun with it!
