We welcome readers to engage with us on various topics related to electronics such as IC chips, capacitors, resistors, inductors, circuit breakers, diode, transistor, module, relay, opticalcoupler, connectors, PCBs, etc. Please feel free to share your thoughts and questions on these subjects with us. We look forward to hearing from you!

Everything You Need To Know About CMOS

Everything You Should Know About CMOS

Usually, electronic devices have to cope with high voltages. However, these high voltages can damage the circuits. In order to avoid this, the circuits are operated at low voltages. CMOS deals with these low voltages by using a complementary set of materials. CMOS stands for “complementary metal–oxide semiconductor.” Essentially, it’s a type of integrated circuit…

How to Solder Wires Together Correctly

How to Solder Wires Together Correctly

It’s more crucial than ever to learn how to solder wires. Homeowners are increasingly repairing appliances such as dishwashers and refrigerators. You can fix minor equipment like electric teapots instead of throwing them away when you know how to solder. With a little discipline, patience, and practice, you can learn how to solder wires for…

Everything You Need to Know About Multiplexing

Everything You Should Know About Multiplexing

Multiplexing is a way of transmitting and receiving information used by telecommunications such as radio, telephone, and television. Multiplexing is a technique for sending several analogs or digital signals over a single transmission line. Multiplexing is mixing data streams, and a multiplexer is hardware used for multiplexing. This article will answer the question, “What are…

Everything you Should Know About SPDT Switch

Everything You Should Know About SPDT Switch

Switches are devices that are used in electrical wiring to change the flow of electricity. Single pole double throw switches are a common component in our everyday lives. They are essential for connecting electrical appliances, fixtures, and devices to power sources. However, few of us know much about these switches. Although they may appear simple,…

PID controller design

Everything You Should Know About PID Controller

A proportional-integral-derivative (PID) controller is an essential tool in the world of electronics. It helps you respond quickly to changes in output and input (loop feedback), which is essential when building complex machinery or sensitive devices. Such a control system is used in measuring various parameters including temperature, speed, and flow among many others. This…

BR1225 and CR1225 Batteries Features and Specifications

CR1225 vs BR1225: What’s The Difference?

The lithium 3.0V coin cell batteries BR1225 and CR1225 are commonly found in dog collars, thermometers, heart rate monitors, keyless remotes, PDAs, medical scales, remote controls, motherboards, and other electronic devices. Both BR1225 and CR1225 batteries have identical physical dimensions, but their chemistry differs, resulting in differing capacity, voltages, operating temperatures, self-discharge rate, shelf life,…
