If we will go back to history the 8051 microcontroller was first invented in the year 1980 by themicroprocessorgiant Intel and gradually it has been accepted worldwide and with the every coming days the importance of the 8051 microcontroller is escalating. When it was invented by the Intel, it...
Let us see come of the very useful pins of the microcontroller with their functions. ALE: As 8051 is based on Harvard architecture. It has separate Program & data memory connected externally. This external memory is access using 16 lines, in which 8 lines are also used as data lines apart...
The main intention of this project is to design a medication reminder using PIC microcontroller. This project helps to remind a patient to take medicine at the arranged time and also displays the name of the medicine. This project is very helpful for old people and also who are very busy. ...
A microcontroller is built for general purpose and it can be used for a variety of applications. It can be interfaced with other components likeRTC, Keypad controller, USB controller, Camera controller etc. inside a single board to form a System on Board (SoB). Image of a 8051 base SoB ...
This project is designed to develop arobotic vehiclethat is controlled by the cell phone. This is based on 8051 microcontroller. The two cell phone controls the robot as per requirement. One cell phone is connected to the robot and another one is user cell. When a key pressed on user cell...
In the below circuit, a three-level voltage inverter is used for obtaining three output voltages depends on DC bus voltage. Single-phase supply is rectified to supply DC power to both microcontroller circuit and inverter circuits.8051 Microcontroller is programmed to produce SVPWM signals which are...
This type of controllers is used in industrial applications for controlling the temperature of devices. It also displays the temperature on 1 LCD displays in the range of –55°C to +125°C. At the heart of the circuit is the microcontroller from 8051 family which controls all its functions...
an open-drain output, it will need to be inverted and then drive the gate of an NFET with the open drain tied to the RX input. See Figure 1. Microcontroller UART Vcc TX RX HDQ HDQ Comunication Circuit For UART Without Open Drain Outputs ...
Also note that the TX and RX of the UART must be tied together. In case the TX output is not an open-drain output, it will need to be inverted and then drive the gate of an NFET with the open drain tied to the RX input. See Figure 1. Microcontroller UART RX TX Vcc HDQ HDQ ...
of wheels, which are placed on the shafts of the two motors. So, the basic control is achieved by controlling the motors. The control circuitry involves the use of sensors to sense the path andthe microcontrolleror any other device to control the motor operation through the motor drivers, ...
