8051

In modern electronics world, touch input is used almost everywhere, whether it can be a mobile phone or an LCD monitor switch. Capacitive touch is the widely used in the touch sensor segment and we previously used capacitive touch with a Raspberry Pi. Here in this project, we will interface touch sensor with 8051 microcontroller AT89S52. If you are new to 8051 microcontoller…

Frequency is defined as number of cycles per second. It can also be defined as reciprocal of total time ‘T’.  In this project we are going to count the number of pulses entering into Port 3.5 of 8051 microcontroller and display it on 16*2 LCD display. So basically we have measuring the frequency of signal at Port 3.5 of 8051. Here we have used AT89S52 8051 chip, and a…

In this project we are going to build an Android Phone controlled robot using 8051 microcontrollers and Bluetooth module. The robot is designed using DC motors and the direction of DC motors will be controlled by the commands received from the android application. The status of the robot is sent back to the Android app. This project will also help for interfacing of HC-05 Bluetooth module…

Radio Frequency Identification (RFID) uses radio frequency to read information stored in a RFID card or tag. In this project we are going to Interface EM-18 RFID reader with 8051 microcontroller and display RFID card number on 16*2 LCD display. This wireless RF Identification is used in many systems like RFID Based Attendance System, security systems, voting machines etc.…

Sometimes people find it difficult to read temperature from analog thermometer because of fluctuations. So here we are going to build a simple Digital thermometer using 8051 microcontroller in which LM35 sensor is used for measuring the temperature. We have also used LM35 to build digital thermometer using Arduino, NodeMCU, PIC, Raspberry Pi and other microcontrollers.…

In our daily life, we see many types of devices for displaying Text, Images and Graphics. LCDs are one of the most popular Display Device in Electronics and used in mostly all the projects which display some kind of information. There are many types of LCDs used in Electronic Projects. We have already used 16X2 LCD in many of our projects and also used TFT LCD with Arduino.…

In this project, we are going to demonstrate making a RTC Clock using 8051 microcontroller.  If you would like to do this project with Arduino, check this digital clock using Arduino. The major component of this project is DS1307 which is a real time digital clock IC. Lets know about this IC in detail. 

ADC is the Analog to Digital converter, which converts analog data into digital format; usually, it is used to convert analog voltage into digital format. Analog signal has an infinite no of values, like a sine wave or our speech, ADC converts them into particular levels or states, which can be measured in numbers as a physical quantity. Instead of continuous conversion, ADC…

Security is a major concern in our day to day life, and digital locks have become an important part of these security systems. There are many types technologies available to secure our place, like PIR Based security systems, RFID based Security system, Laser security alarms, bio-matrix systems etc. Even now, there are Digital locks which can be operated using our smart…

Imagine that you can control the electronic appliances of your home from anywhere inside the house, just using your Smart phone. In this project, we will use wireless Bluetooth technology to control the Home Electronic Appliances through a Android Phone. Bluetooth has a range of 10-15 meters, so that you can switch ON and OFF any electronic appliance within the…

In this project, we are going to develop a PIR sensor and GSM based home security system. This project is developed using 8051 microcontroller. It can be used to detect any intrusion in houses and offices and send the alerts on cell phones. Let us know how to develop this system, step by step.

In this project, we are going to develop an RFID and keypad based Security system. This project is implemented by using 8051 microcontroller. RFID Tecnology (Radio Frequency Identification and Detection) is commonly used in schools, colleges, office and stations for various purposes to automatically authenticate people with valid RFID tags. Here we will check the RFID…
