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 […]

Controlling LEDs with voice command seems to be a difficult task, but it’s easy and you can quickly build it. We just need an Arduino UNO to serially communicate with HC-06 Bluetooth module and a smartphone to send voice command to Bluetooth module HC-06. For receiving voice command we are using “Arduino Bluetooth Voice Controller”
Voice Controlled LEDs using Arduino and Bluetooth Continue Reading
This IoT system monitors the soil moisture using Arduino and sensors. Data are sent to an IoT cloud platform to access it anywhere.

In this project, we will use the digital pins and screen of the 4Duino to create a 5×7 LED matrix controller with a user graphical interface. An LED matrix is essentially many LEDs packaged in a dot grid format in order to produce pictures or large text. They’re commonly used for signage purposes in the

By using arduino and IR Receiver TSOP 1738 (in our project, you can use any ir receiver available) we can decode any infrared remote code into hex or some other format. Before constructing the circuit check datasheet of IR receiver having in your hand, hence you can connect proper bias pins and output pin. Step

Most modern electronics, from flat-screen TVs and smartphones to wearable technologies and computer monitors, use tiny light-emitting diodes, or LEDs. These LEDs are based off of semiconductors that emit light with the movement of electrons. As devices get smaller and faster, there is more demand for such semiconductors that are tinier, stronger and more energy
Scientists build thinnest-possible LEDs to be stronger, more energy efficient Continue Reading
Description In this tutorial you will set up and turn on a single LED. Note that this code can actually be executed with just the Arduino and no other components as in Figure 5. If you notice, next to pin 13 is a tiny LED on the board. If you execute the code below, you
