10-Channel Multiplexer Circuit using 555 IC

Engineeering Projects
multiplexer circuit for 10 channel

This project is a low-cost multiplexing system for ten channels. The project 10-channel multiplexer circuit using 555 IC can be used as an add-on device for a single point indicating system. Both auto and manual selection are incorporated with the visual indication of channel number. It is suitable for signals concerning a common line. However, for double-ended signals, the input LOW lines can be made common and the input High lines can be multiplexed. This can be used for thermocouple signals, strain gauges, and any other AC/DC signal in the…

Power Saver Circuit Diagram using PIR

Engineeering Projects
PIR sensor

People are always in rush these days and they forget important things like turning the lights off in addition to a few other electrical devices. This results in either an electrical explosion or wastage of power. And, so to eradicate such issues, we have developed a Power Saver Circuit Diagram based on a Passive infrared sensor that employs a PIR motion sensor to detect the presence of human beings and as they leave the room, turn any electrical appliances connected to the circuit after a certain defined time interval. The…

Audio Amplifier Circuit Using 555 IC

Engineeering Projects
Timer IC 555 based audio amplifier IC

As being electronics hobbyists we all know about timer IC 555. Timer IC 555 is one of the most popular IC of all time because of its application. This IC has various applications like clock pulse generator, time delay circuit, etc. Here, is another application of 555 timer IC i.e. Audio Amplifier using 555. We are going to use a 555 timer IC rather than a conventional amplifier IC because it has unique features like low audio distortion and high efficiency with a high base. PWM is the method by…

RJ45 cable tester using 555 IC

In the field of networking, RJ45 is the most common cable used. This cable consists of multiple wires clamped within a single plastic tube and in such a case, there is a high probability that the project implementing RJ45 will not work efficiently. Rather than isolating the entire circuit to check the fault, it is considered wiser to test the RJ45 cable which causes failure most of the time. And, here is the tester circuit called “RJ45 Cable Tester Circuit” which is used to test RJ45 cable either in straight-through…

Servo motor tester circuit using 555

I believe testing circuits are a must for project geeks since these testers save so much time in debugging circuits. People invest all their efforts and spend so much time completing one project but most of the time they don’t get the desired output. There can be multiple reasons behind this and generally, it is because the components like servo motors are at fault. The project Servo Motor Tester Circuit Using 555 IC was used in the project after isolating it from the project and helping us to detect if…

DIY Hearing Aid Circuit using 555

Engineeering Projects
diy hearing aid circuit

The general circuit of Hearing Aid available over the internet used a normal transistorize circuit thus it consumes more power. So, here we are concentrated to design a circuit that consumes less power, DIY Hearing Aid Circuit using 555. For that, the circuit present here of DIY Hearing Aid Using 555 has an automatic triggering mode which consumes 96 mA at the time of amplifier trigger or you can say when sound is detected else it consumes only 6 mA which is very less. Other than less power consumption the…

circuit diagram of rotation sensor using 555IC

In this section, we discuss another application of the most popular IC, the 555 timers. Introduced in 1972 by the Signetics Corporation as a bipolar integrated circuit, the 555 is also available in CMOS technology and from several manufacturers. There are various projects we had already posted in the timer IC 555-based projects section. Now, we have come up with another interesting project called rotation sensor using the most popular IC of all time 555 Timer IC. When more conveyors or equipment are used in the processing system and anyone…

circuit diagram of DIY strobe light

Here is one another application of one of the most versatile IC NE555, the DIY Strobe light circuit. A strobe light is also called a stroboscopic lamp and is used to produce a regular flash of light. The general strobe light has a very high flash energy of about 150 joules and very few milliseconds of discharge time. Due to this property, it emits flash power of several kilowatts. Various types of strobe light circuits using xenon flash lamps, flash tube, LEDs, etc. posted on bestengineeringprojects.com are listed below:- High Brightness…
