Active SMD Components E-Databook
A new data book in electronic format about the SMD-codes for active electronic components from a the well known author Eugene Turuta.This e-book includes now 75.800 SMD-codes for different semiconductors like diodes, thyristors, transistors and ICs.You can find in this e-book:- The separate chapters for components with 2-pins, 3-pins,4-pins, 5-pins, 6 and [...]
What is Proteus VSM?
Proteus Virtual System Modelling (VSM) combines mixed mode SPICE circuit simulation, animated components and microprocessor models to facilitate co-simulation of complete microcontroller based designs. For the first time ever, it is possible to develop and test such designs before a physical prototype is constructed.
This is possible because you can interact with the [...]
VirtualBreadboard (VBB) is for designing and testing embedded software in high-level interactive circuit simulations and rapidly prototyping hardware from those designs. Compared to other simulators many people find the high level approach taken VBB easier to use and much faster to model and test out new ideas and circuit variations.

TXD and RXD lines are high level while idle – this is why LEDs are ON. During data transmission LEDs are blinking.

USB Powered power Amplifier for you PC
I faced this article when I was looking for simple solution how to increase the output of my integrated sound card of my PC. I don’t know why, but the sound level of it decreased so I can’t normally listen with my headphones. So this article is about how [...]

This project allows instant start sequentially but a dozen low-voltage lamps 12 V / 60 W, and makes them fade and always sequentially (but slower). This system has been designed to meet the demand of a visitor who wanted ten recessed low voltage spot in a driveway to his house, with the following function: – [...]
This circuit allows switching on a LED when the battery voltage (12V) drops below a certain threshold. The operating system is based on a comparison of tension, which comes in a zener diode. If the supply voltage is 12V and the zener diode is a 10V model (this is the case in the diagram), we [...]
This is a good looking and practical device that can be useful in many areas where countdown timer is needed. This project is based on the PIC16F84A microcontroller. The time range can be adjusted between 1 and 999 seconds. This project has 3 buttons and one of them is named Set Button. In order to [...]
A VU meter is often included in audio equipment to display a signal level in Volume Units; the device is sometimes also called volume indicator (VI). In this project we are building a basic and low cost LED VU Metre circuit . The extent (range) display is -18 dBu to +3 dBu, spread over [...]
Today we have a new category “Projects” and a new electronic project 12 Channel LED Chaser with PIC16F84A.
This project is based on the popular PIC16f84A micro-controller.The heart of this project LED chaser is the PIC16F84A PIC microcontroller.A 4MHz crystal and capacitors C1 and C2 22pf is used for providing clock pulses to the micro-controller. The [...]
