Here we are going to discuss a simple timer IC 555 project. The 555 timer IC can be used as an audio amplifier with an astable multivibrator configuration. It functions to carry out pulse width modulation (PWM) of the audio signal. The Current(I) capacity of the 555 timer…
MOSFETs (Metal Oxide Semiconductor Field Effect Transistor) are of four different types or modes. They may be enhancement or depletion mode or maybe N channel or P channel. How does a MOSFET work? Here we provide a Java applet tutorial of N…
A summing amplifier or an adder is used to sum two signal voltages. A voltage adder circuit is a simple circuit that enables you to add several signals together. It has a wide variety of applications in electronic circuits. For…
Here circuitsgallery comes with the simplest mini audio amplifier circuit schematic using LM386 low voltage audio power amplifier IC. This circuit is applicable to power medium-sized speakers from a music player that can only drive earphones (lm386 headphone). The LM386 is a low voltage power amplifier…
You can easily plot different functions using MATLAB. To plot a 2D function in MATLAB you must first choose an independent variable. Let it be ‘x’. This variable will form an axis of the plot, more likely the horizontal or…
The name MATLAB stands for MATrix LABoratory. It is the fourth-generation programming language and is developed by Mathworks Inc., USA. MATLAB is great for doing array manipulation, doing specialized math functions, and creating nice plots quickly. It is a Matrix-based powerful…
You are now going to be introduced with a new audio power amplifier schematic built around TIP Darlington pair transistors. You can use this circuit for home audio power amplifiers and car audio amplifiers. The TIP142 and TIP147 Darlington pair transistors form a push-pull high power amplifier configuration while the two BC558 PNP transistor…
Have you ever thought about home security? And implementing your own home security alarm systems? It’s one of the simplest and most interesting circuits for electronic beginners. Our new home security equipment uses an LDR (Light Depended Resistor) to detect security problems. Theft attempts and other…
Hi there! Today let’s make an Arduino project without having a real Arduino board! Yes, it’s possible by dint of Arduino simulator using Proteus library. Maybe you have already seen (or will see) Arduino programming in some of my articles. Arduino is…
