Resistors and Capacitors are types of passive electronic components. The basic unit of resistance is the ohm (Ω) and capacitance is Farad.
Standard base resistor values are given in the following tables for the most commonly used tolerances (1%, 2%, 5%, 10%), along with typically available resistance ranges.
In 1952 the IEC (International Electrotechnical Commission) decided to define the resistance and tolerance values into a norm, to ease the mass manufacturing of resistors. These are referred to as preferred values or E-series, and they are published in standard IEC 60063:1963. These standard values are also valid for other components like capacitors, inductors and Zener diodes. The preferred values for resistors were established in 1952, but the concept of the geometric series was already introduced by army engineer Renard in the 1870s.

The electronic color code is used to indicate the values or ratings of electronic components, usually for resistors, but also for capacitors, inductors, diodes and others. A separate code, the 25-pair color code, is used to identify wires in some telecommunications cables.
Standard Resistor and Capacitor values with IEC and EIA code is explained in previous post.
This tool is used to decode information for color banded axial lead resistors. Select their colors to determine the value and tolerance of the resistor.

The circuit given here is of digital voltmeter with LED 7-segment display using the ICL7107. It measures voltage from 0.00V to 99.9V. ICL7107 is a 3 1/2 digit A/D converters with LED 7-Segment Driver.
The Intersil ICL7106 and ICL7107 are high performance, low power, 31/2 digit A/D converters. Included are seven segment decoders, display drivers, a reference, and a clock. The ICL7106 is designed to interface with a liquid crystal display (LCD) and includes a multiplexed backplane drive; the ICL7107 will directly drive an instrument size light emitting diode (LED) display.

In this tutorial we are discussing on how to use arduino with Proteus simulation software. We assume that you have installed Arduino Library in your Proteus software. for installing arduino library in Proteus visit “How to add library in Proteus?” We will learn it by taking led blink example. Continue reading Getting Started with Proteus
Proteus is simulation and PCB designing software. Many times we need to simulate different circuits before we actually develop it, This tutorial shows how to add library in Proteus 7 and Proteus 8.
Following are the simple steps to add Library in Proteus
Step 1: Download Proteus library zip file example ARDUINO Proteus library
Step 2: Unzip library folder. You will see two files names as *.IDX and *.LIB in some cases third file is *.HEX.
In our example it is ARDUINO.IDX and ARDUINO.LIB
Step 3: Copy and paste these files in LIBRARY folder of Proteus
If you are using Proteus 7 Professional, then the library folder link will be something like this: “C:\Program Files (x86)\Labcenter Electronics\Proteus 7 Professional\LIBRARY“
If you are using Proteus 8 Professional, then the library folder link will be something like this: “C:\Program Files\Labcenter Electronics\Proteus 8 Professional\Data\LIBRARY”
Step 4: Close Proteus Software and reopen it to check it. That’s all.
You can find that adding library to Proteus, Arduino, Eagle is same just copy and paste the library files at proper location.
