What is “C” Programming

Before we can start writing serious C programs, it would be interesting to find out what C really is, how it came about, and how it compares to other computer languages. In this chapter we will briefly present these issues. Four important aspects of any language are how it stores data, how it operates on … Read more What is “C” Programming

Electronic Code Lock Circuit Using 555 Timer IC

Digital code locks are very popular in electronics, where you have to enter a certain “code” to open Lock. This type of Lock requires a Microcontroller to compare the entered code with the predefined code to open the Lock. We have already built these types of digital locks using Arduino, using Raspberry PI and using … Read more Electronic Code Lock Circuit Using 555 Timer IC
