In this guide Sanket Gupta @ octopart.com explains how to select a resistor from a range of common resistor types. In this blog, we will explain all the different types of resistors, their merits and demerits, and popular applications. We have included some recommendations for...

Deepak Behera, Sumit Varshney, Sunaina Srivastava, and Swapnil Tiwari discuss about using an oscilloscope to create eye diagrams and quickly evaluate system performance and gain. Accelerating data rates, greater design complexity, standards requirements, and shorter cycle times put...

Adafruit has published some new Business card-sized references for Arduino and basic electronics. Adobe Illustrator format files are available for download on their github.com repository. Adobe Illustrator format. These are sized for Overnight Prints‘ standard business card...

Here is a PDF document written by D. Grover, explaining how to understand a manufacturer's datasheet. It goes through the 555 timer IC datasheet and gives an explanation on various parts. How to Read a Datasheet -...

In this video "KF5OBS" showing us how to generate a PWM signal that's behaving proportionally to analog control signal. Generating PWM Signals -...

a1ronzo @ learn.sparkfun.com explains us the importance of pull-up resistors and when and why they are used in digital circuits. Pull-up resistors are very common when using microcontrollers (MCUs) or any digital logic device. This tutorial will explain when and where to use pull-up...

by Stefano Salvatori & Pietro Oliva @ edn.com: This Design Idea mates a precision current source IC with precision difference amp chips to create a programmable current source or sink. The resistor-programmable current source/sink in Figure 1 illustrates the basic topology,...

by Maurizio @ dev.emcelettronica.com: Our body is built with biological tissue. The tissue that can generate or detect bioelectrical signals is called excitable tissue. Some examples of this tissue (and its cells) are: neurons and muscular tissue. Neurons are responsible of...
