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…

仅通过使用8051（89C51,89C52）微控制器的内部计时，才能提供适当的延迟（例如1秒或1分钟）。8051系列微控制器在16位计时器0＆Timer 1中具有两个构建，有些也有一个额外的计时器计时器3。您可以使用它们来生成延迟，UART的baud速率用于串行通信或触发事件源执行…

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…

这篇文章是关于在89C51 MicroController的帮助下在16×2字符LCD显示屏上显示自定义乌尔都语字符。以前，我讨论了“如何使用8051（89C51,89C52）微控制器显示16×2 LCD显示器上的自定义字符？”。本教程是通过在上述教程中遵循相同的步骤来制作的。唯一的区别是，在…
