What's awesome about this is that it structures your system to react quickly and efficiently to important events that aren't easy to anticipate in software. Best of all, it frees up your processor for doing other stuff while it's waiting on an event to show up.

Getting started with basic electronics is easier than you might think. This Instructable will hopefully demystify the basics of electronics so that anyone with an interest in building circuits can hit the ground running. This is a quick overview into practical electronics and it is not my goal to delve deeply into the science of electrical engineering.

In this project we are going to interface a ROTARY ENCODER with ARDUINO. ARDUINO UNO is an ATMEGA controller based development board designed for electronic engineers and hobbyists. In ARDUINO we have 20 I/O pins, so we can program 20 pins of UNO to be used as either input or output.

As per the reader’s request, here is the making of the IR Sensor Module. An IR Sensor module is a sensor that transmits and receives infra-red rays when a surface or object is detected. It is a multipurpose sensor, which can be used in line following robot, obstacle avoiding robot, edge avoiding robot, etc.

IC CD4017 is a CMOS decade counter IC. It can produce output at the 10 pins sequentially, i.e. it produce output one by one at the 10 output pins. Explore below some interesting electronic circuits based on IC CD4017.
