TVOC and CO2 Measurement using Arduino and CCS811 Air Quality Sensor

Sadly, in the name of progress, we have polluted the air, water, soil and the food we eat”. So monitoring the air quality is very crucial now days because of pollution. For designing an air quality monitoring system we need durable and reliable air quality sensor. Although there are many Air Quality parameters but the most important are CO2 and TVOC. So for sensing CO2 and TVOC, we are using CCS811 Air Qual ...

Review: ScanaQuad – a super-small logic analyzer

If you are mainly involved in designing or repairing digital devices, a logic analyzer is more useful than an oscilloscope for tracing signal through circuits. However, does this mean you should rush out and buy a logic analyzer? The instruments from the leading manufacturers are too expensive for home use or startup businesses, and the low-cost alternatives don’t do what you want or have half-baked softwar ...

Interfacing Arduino with MATLAB – Blinking LED

In this project, we are going to learn, How to set up hardware support for Arduino in MATLAB software. How to control an Arduino using MATLAB code. We normally use Arduino IDE to write and upload codes to Arduino. The advantage of MATLAB is, it uses a high-level programming language which is easier than C / C++. The other advantage of using MATLAB is, we can see the results of I/O operations quickly (withou ...

Better LEDs with just a trick of the light

Light propagating in a layer of scattering nanoparticles, shows the principles of diffusion - like tea particles in hot water. The deeper light is penetrating into the layer, the lower the energy density. Scientists of University of Twente’s Complex Photonics Group, however, manage to turn this falling diffusion curve into a rising one, by manipulating the incident light. More light energy inside an opaque ...

Walabot Object Detection

A PC application that talks to the Walabot PRO, Arduino and NeoPixels! Story Welcome to my Walabot project I will split this project in different parts 1. Get to know the Walabot and a setup. This includes data readout and send it to an Arduino. 2. Gather the data that is needed for the calculations and create an image with this data 3. Convert the data to an object Getting started with the Walabot I've mad ...

Automatic Cool Blue Lights For Your Room

Build a Automatic Cool Blue Lighting System using Arduino, that will turn on when you walk into the room and turn off when you walk out. Story Let us do something fun during this weekend shall we? Something less costly and easy for everyone to do. This time, why don't we play with lights? Let us build a cool blue Automatic Lights just like neon, that will turn on when you walk into the room and turn off whe ...

Controlling Multiple Servo Motors with Arduino

Using one or two Servo with Arduino is Easy but what if we want to use more than one Servo Motors? Here, we are going to show you that how to control Multiple Servo Motors with Arduino. Connecting multiple Servo Motors with Arduino seems to be easy and but if we connect all the Servos to Arduino supply pins then they won’t work correctly because of lack of enough current to drive all the motors. So you have ...

Graphene Patterned at Room Temp

LAKE WALES Fla.—Graphene is easily grown with chemical vapor deposition (CVD) on copper foil, but a simple way of etching out the necessary circuit patterns and transferring them to a non-metallic substrate has eluded engineers. Now researchers at the University of Illinois (Urbana-Champaign) claim to have a one-step room temperature process for quickly patterning and transferring graphene circuits to flexi ...

DIY electronic RFID Door Lock with Battery Backup

About Burglars Recently the Spiegel published an article about burglars in Germany: Burglars prefer the dark months. In december the insurances report 3 times more housebreakings than in july. The police reports that it is very difficult to find the delinquents. Mostly there are no witnesses and no traces. Only in 2,6% of the housebreakings the culprit can be condemned. Burglars do not only break into house ...

Arduino with ESP8266 – Reading Data from Internet

The ESP8266-01 has been a great module to quench all our thirsts for IOT projects. Since its release, it has developed a strong community and evolved into an easy to use, cheap and powerful Wi-Fi module. Another open-source platform which is much more popular is the Arduino, it already has tons of projects built around it. Combining these two platforms will open up doors for many innovative projects, so in ...
