Here is a simple solid-state relay (SSR) driver circuit using a transistor. An SSR is similar in operation to a traditional electromagnetic relay with movable/physical contacts. It employs an optical semiconductor, called photocoupler, to isolate input and output signals;...
Retailers are starting to acknowledge the role of IT as an enabler. Basically, it can speed up processes and deliver cost-saving benefits to companies You are out for an evening stroll in the market. One of your shirt’s fancy button...
This project presents an Android app to generate an alert (alarm) on a smartphone when temperature of the process under consideration exceeds user-defined maximum temperature. Alarm and annunciator instrumentation systems are widely used in the control room of process plants....
In general, human resource (HR) services include a large amount of time spent on standard onboarding processes for new employees, triaging common questions and employee requests, and basic benefits management. Artificial intelligence (AI) presents an opportunity for HR to...
A simple explanation for the working of an ideal diode circuit based on P-channel MOSFET and PNP transistor is presented here. The typical voltage required to turn on a diode is forward voltage. An ideal diode should have zero...
With cloud adaption growing at a massive speed today, staying updated with latest technologies is the need of the hour. Manoj Sharma, HR director, NetApp India, talks about why developers should upskill themselves, skillsets in demand today, open source...
Presented here is an Arduino-based dish antenna controller to align the position of a satellite dish antenna by setting azimuth and elevation angles. The dish antenna should always point to a specific satellite in space to receive maximum signal....
Wheelchairs are useful for people for whom walking is difficult or impossible due to some illness, injury or disability. There are different types of wheelchairs. Manual wheelchairs are pushed using their handles. Motorised wheelchairs, are driven by joystick. Voice-controlled wheelchairs...
Infrared (IR) remote-controlled RGB bulbs available in the market are extremely expensive. Here is a simple, easy-to-build and inexpensive circuit built using Arduino Uno R3. The project demonstrates how to turn on/off or vary the colours of an RGB...
Artificial intelligence (AI) is coming to a point where action, not talk, is needed. While there are fears and inflated expectations of what AI can do, much of it is hype and a far cry from what it can...
