An Infrared light-emitting diode (IR LED) is a special purpose LED emitting infrared rays ranging from 700 nm to 1 mm wavelength. Different IR LEDs may produce infrared light of differing wavelengths, just like different LEDs produce light of different colors. IR...
With the introduction of artificial intelligence and hybrid technologies, the future of drones is not just limited to taking great live aerial photos and videos, now these can also be used for personal transportation and commercial aviation, and even...
Going up or down a staircase can be a challenging task at night, especially for kids and elderly people. This Automatic LED Staircase Light circuit lights up two LEDs, one at each end of the staircase, for a couple...
The ability of FPGAs (field-programmable gate arrays) to be reprogrammed to achieve the desired application or functionality after manufacturing makes them ideal for today’s constantly evolving applications that impose strict restrictions on power and latency while requiring high compute...
The concept of drones/unmanned aerial vehicles (UAVs) has been constantly developing with technology getting more advanced these days. Earlier, this technology was utilised only for military purposes but for the past few decades, drones have become easily available to...
This article describes the basic installation of an RFID and password-based access control system. Access control systems allow only the authorised persons to enter or exit the premises. An access control system may include locks, turnstiles, biometric readers, face...
This is an extract from a speech presented by Nikhil Bhaskaran, Founder, Shunya OS, at iotshow.in 2019. Shunya OS is an operating system that optimises AI libraries for embedded systems, to enable developers to build AI on edge solution...
Quantum dots (QDs), popularly used as QLED displays in TVs, are now playing a crucial role in the development and transformation of the medical field. QDs are now being used in advanced and intelligent applications like bio-imaging, drug delivery,...
Quantum computing is considered an efficient and precise way of solving complex problems which may not get easily solved by even the largest supercomputers in fields like chemistry, medicine, finance, and logistics. In comparison to the rest of the...
In this project, the Arduino Uno is configured as a square wave generator with user-selectable control of the frequency and duty cycle. The operating range of the system is up to 10kHz. The desired frequency and duty cycle of...
