Hyper terminal is a program through…

In this tutorial i am going to teach you how to interface graphical lcd 128×64 with 8051(89c51,89c52)microcontroller. 128×64 means that lcd has 128 coulombs and 64 rows. Which means you can make your desired image or text in 128×64 matrix square. Graphical lcds comes in many sizes, they also differ in characteristics. Some can be…

This is a simple project on how to display/print your name on 16×2 lcd using 8051(89c51) microcontroller. Character lcd’s comes in many packages 16×2 , 8×1 ,16×1 ,8×2. All the lcd’s performs actually the same function, display data that we send to them. Displaying data on 16×2 lcd is not an easy task, its also not…

Controlling led brightness or fading an led using 8051(89c51,89c52) microcontroller is not an easy task. In depth knowledge of 8051 microcontroller timers and their registers is required to fade or control led brightness with 89c51 microcontroller. So in this project/tutorial i am going to teach you how to fade an led with 89c51 microcontroller? How to…

Here is a simple project for counting people, vehicles or anything passing through a certain place. Anything when physically crosses the barrier of our embedded system DIY project will increment our counter. The counter is bidirectional means it can count/increment if the object crosses its barrier from either left or right direction. The basic idea…

Giving a proper delay like 1-Second OR 1-Minute is possible only by using internal timers of 8051(89c51,89c52) microcontroller. The 8051 series microcontrollers have two build in 16-bit timers Timer 0 & Timer 1, Some also have an extra timer Timer 3 . You can use them to generate delays, baud rate for UART for serial Communication OR trigger an event source to execute…

In this tutorial will learn how to interface ADC0804(Analog to Digital Converter) with 8051(89c51,89c52) microcontroller. 8051 microcontrollers are pretty old and don’t have a build in analog to digital converter in them unlike their new rivals(Arduino, Pic microcontroller and many more). Hence we can not directly measure any analog value (voltage, Temperature present in the…
