The LEDs are connected via sockets J3 to J12 (only one row LEDs is shown on the schematic) and I found that it's cheaper to use a 28 pin IC sockets cut in half than regular 40 pin sockets. Of cours...

For building the digital meter contains accuracy higher than the common meter. The heart of this circuit is IC-ICL7107 old, who is now much cheaper. This IC is a 40 pin model as shown in Figure 1 W...

A poor people and the beginners it has a heart. We would like to propose a electronic VU meter projects on economy model that has stereo each side are 5 LEDs. This projects, unless will be used as ...

This project is a LED signal Meter that easy and very cheap, can drive 9 LED display,The LB1409 is used as base of this circuit makes them has small size. This our circuit is simple that is designe...

The NE604`s signal-strength indicator section is used, based on an internal logarithmic converter. This enables a lineardecibel scale so that the moving-coil meter (shown in the diagram) can be rep...

Analog Frequency Meter Circuit using NE555 This 1-kHz linear-scale analog frequency meter circuit uses the 555 as a pulse counter. PARTS.
