To turn LED ON using 8051 Micro-Controller

SOFTWARE: KEIL MICRO VISION 4

SIMULATOR: PROTEUS 8.0

CIRCUIT DIAGRAM:




CIRCUIT WORKING:


This project is about turning on the led which is connected to port 1.0 of port 1.
I have designed this circuit as a current sinking circuit.So in order to turn ON the led,I have provided 0V(logic 0) on port 1.0.



PROGRAM:


#include<reg51.h>

sbit led1 = P1^0;

void main()

{

P1=0xfc; // set Port 1.0 as output

led1=1; // initially turn off the led

while(1) //continuous loop

{

led1 = 0; // turn on the led1

}

}



PROGRAM DESCRIPTION:


At starting I have make turned off the led by providing logic 1 (Port1.0).Then for a continuous process,I have used while loop.After that I have turned ON the led by providing logic 0.

Digital Thermometer using 8051 and ADC 0808 Interfacing With 8051

SOFTWARE: KEIL MICRO VISION 4 SIMULATOR: PROTEUS 8.0 CIRCUIT DIAGRAM: WORKING: Here,Temperature is taken from LM35 temperature sensor.LM35 converts surrounding temperature into analog voltage(equivalent to temperature).This analog voltage is provided to ADC0808 for digital conversion. After digital conversion,final temperature get displayed on LCD display. LCD(16X2) DISPLAY: RS,RW,EN pins are connected to P2.5 to P2.7 of 8051 respectively. Data pins (D0 to D7) are connected to P3.0 to P3.7 of 8051 respectively. LM35 SENSOR: VCC pin is connected to 5 v supply. VOUT pin is connected to IN0 channel of ADC 0808. On the VOUT pin we get equivalent voltage with respect to the surrounding  temperature. Temperature change is 10 mv/°c. GND pin is connected to GND. ADC 0808: VCC pin is connected to 5 v supply. VREF(+) pin is connected to 2.56V supply. VREF(-) pin is connected to GND. OUT8(LSB) to OUT1(MSB) pins are connected to P1.0(LSB) to P1.7(MSB) respectively.i.e. OUT8 pin is connected to P1.

how to display numbers on lcd?

In this article I have written about how number get displayed on lcd. Lcd only displays character ranging from '0' to '9' ( in terms of numbers). So the question is how to display numbers which are greater than 9 ? If we want to display any number which is  greater  than 9 on an lcd then decompose(break) the number and add 48 to each separated digit of that number and send the resulting value one by one to the lcd. Here I have taken four digit number as an example. Suppose I want to display 1352 on lcd. First basic step is initialization  of lcd. Please refer my article about lcd display interfacing with 8051  to know lcd display interfacing. ( http://embeddedprojects222.blogspot.com/2020/07/lcd-interfacing-using-8051-micro.html ). Then the next step is decompose(break) the number. Procedure to decompose(break) 4 digit number: 1.First divide the number by 1000.So we get first number.  Ex.1352/1000=1; 2.Divide the number by 1000 and take the remainder of the

To display custom characters on the lcd using 8051 micro-controller.

SOFTWARE:   KEIL MICRO VISION 4 SIMULATOR:   PROTEUS 8.0 CIRCUIT DIAGRAM: WORKING: This project is about displaying custom characters on the lcd.Simple meaning of custom character is the character which is not available on the keyboard or which is made by modifying original characters. In the lcd display,to display characters which are already available in the form of ascii value (from 'a' to 'z' or any other characters) we do not need to do anything.By sending the ascii value or sending the character directly to the lcd we can able to display those characters(which are already available) on the lcd. In the lcd display,there is one controller which control all the operations of the lcd.Lcd controller has a memory called  CG-RAM(character generator random access memory)  which is used to create and store the custom character. Size of the CG-RAM is 64 bytes. At a time we can able to display 8 custom characters(for 5*8 matrix) and 4 custom characters(for 5*10 matrix) on th
