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.

Measuring temperature is one of the most common technique used because it is important for many operations and tasks to be performed like in any industries where heaters are used, heat up to a certain temperature is required. When it comes to sensing temperature, a temperature sensor is used that is installed at a place whose temperature is to be sensed. The temperature of that place can be monitored through internet using internet of things. Continue reading IoT Based Temperature Monitoring System
7-segment displays are most popular in panel meters, It can show direct numerical value on display, It’s cost is low and display size bigger than LCD’s. Lets interface four digit display, most of the time four digits are enough to display data.
We are making a Voltmeter using four digit 7-segment display, for this IC 74HC595 shift register is used instead of 7448 decoder, use of shift register gives few advantages such as you can display sign, few alphabets and control decimal point location.

HX711 Load Cell Amplifier, Weighing Scale Design
In this arduino tutorial of HX711 Load Cell amplifier interface. We are interfacing 40Kg load cell to the arduino using HX711 Load cell amplifier module. HX711 is a precision 24-bit analogto-digital converter (ADC) designed for weigh scales and industrial control applications to interface directly with a bridge sensor. The input multiplexer selects either Channel A or B differential input to the low-noise programmable gain amplifier (PGA). Channel A can be programmed with a gain of 128 or 64, corresponding to a full-scale Continue reading HX711 Load Cell Amplifier Interface with Arduino
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.
