Electronic Security System With RTC and User Define Pin Code

Hi Guys! This is a project that I made using pic microcontroller its an Electronic PIN Code Security System with real time clock and user define pin code features, this page contains all the details to make one yourself. ITS WORKING AND CONCEPT: Well by turning Security System on, it will ask for a PINCODE to open gate, (its 140595) if you enter it correct, the door will open. Door is opened for 1 min only, ...

How to create custom characters on 16×2 LCD using PIC18F4550

The 16x2 character LCD can also be used to display custom characters other than numerals, alphabets & special characters. Refer LCD interfacing with PIC. Some special shapes like hearts, arrows, smileys etc. can easily be displayed on the 5x8 pixel pattern of character LCD. These shapes are first stored at a special location in LCD’s controller and then displayed on the LCD module. This procedure has be ...

4 Bit LCD interfacing and programming with PIC Microcontroller

LCD displays operate in two modes 4 bit and 8 bit mode. We all might have been familiar with 8 bit mode which is used widely in several systems. But 4 bit mode is something which many of us is not aware of. This mode has some advantages over the 8 bit mode out of which reduction of dedicated data pins is most important. This tutorial will teach you 4 bit LCD interfacing in 4 bit with your controller as well ...

2-wire LCD interface using PIC16CF84

Alphanumeric LCD displays have become very popular for microcontroller applications because they can add a lot to a project in a variety of different ways. A text message giving the user instructions as well as feedback can make the application seem much more "professional" and easy to use. I like to use LCD's to help debug applications, with breakpoints set to display variable and I/O conditions and they a ...

DIY 32ch FPV 5.8ghz LCD

If you’re like me, you don like buying stuff that’s ready-to-go, but rather build one yourself. We usually spend more money, but it’s way more satisfying I really didn’t want to buy an overly expensive 32ch FPV LCD receiver, so I made my own DIY 32ch FPV 5.8ghz LCD, that is compatible with EVERY transmitter on the market now.First, crack open that LCD, and look what’s inside. I desoldered the wires, and too ...
