The Industrial Internet of Things (IIoT) enables a high level of automation within manufacturing and processing facilities. It helps companies achieve real progress to improve efficiency, productivity, and output quality. This is the heart…
In this article, we will be making an IoT-based pre-paid electricity system and learn exactly how that works. We will create a meter which will monitor the electricity usage and report to a monitoring server (which we will also create) for bills. In an ordinary electricity system, bills come after the usage, and then we…
In previous tutorials of this series, we saw how to vary the intensity (brightness) of LEDs using the PWM output of ATtiny85. This tutorial shall take it to the next step by varying LED brightness using a potentiometer (pot). The pot will give an analog output of 0 to 5V. ATtiny85 has an inbuilt ADC…

CUI Devices Miniature Slide Switches are available in package sizes as small as 10mm x 2.5mm x 5.9mm. These mini slide switch types feature a 2.54mm pitch, raised or flat (flush) actuator levels, SPDT circuits, and on-on switch functions. Options include gull-wing or PC pin terminations, surface-mount or through-hole mounting styles, and vertical or horizontal…
As soon as we come across the word robot, we tend to imagine a metallic structure with arms and legs carrying a human-like appearance and running errands for our help. However, in actual terms, it’s just a machine operated externally or through a controller embedded within and doesn’t necessarily look like a human. Technically, robotics is a branch of Science and Engineering which deals with designing, constructing, and operating robots as well as computer systems for their control, sensory feedback, and information processing.Interestingly, the concept is almost as old as the hills with the first robot dating back to 350 BC, built in the form of a mechanical bird, by a Greek mathematician named Archytas. Although the term was coined ages ago, the actual potential of the fully autonomous robotics was realised in the second half of the 20th century.

This article discusses about a simple circuit that can reproduce the sound signals captured through a microphone on a loudspeaker. The microphone is a device which is used to capture sound signals and forms an essential part of most of the electronic gadgets. The microphone converts the sound signals in the environment to their corresponding electrical signals.
