MICROCONTROLLER BASED AUTOMATIC ROOM LIGHT CONTROLLER
This project involves an automatic room light controller with a bidirectional visitor counter using a microcontroller. It is designed to manage room lighting and accurately count the number of individuals present. When a person enters the room, the counter increments...
89c51 ds1820 based digital thermometer
The hardware configuration for utilizing multiple 1-Wire temperature sensors, such as the DS1820, is straightforward. Communication between the microcontroller and the temperature sensors occurs over a single-wire bus, which can also supply power to the devices. An extensive number of...
Driving circuit schematic
The driving circuit depicted in Figure 18-12 consists of a connection between the driving portion, the microcontroller, and the air conditioning operation components of the bridge. The microcontroller's digital signal levels from ports P4.0 to P4.3 (approximately 12 feet) and...
Robo Atmega328p project
This project was designed to introduce a friend to microcontrollers and circuits using various functionalities and spare parts. A PS2 numpad was utilized as the key entry mechanism, which was found at a thrift store and included the necessary connector....
Electronic TIC TAC TOE
This project is not to introduce Tic Tac Toe. Everyone knows this game. It is to introduce two features: bi-coloured LEDs, microcontrollers, and the skill of writing an ALGORITHM. You can use the project to learn the skills of creating...
AirBorn Electronics project
Embedded system design engineers create examples of their work from the 1990s era.
Embedded systems have evolved significantly since the 1990s, and the design work from that period reflects the technological limitations and innovations of the time. Engineers in this field...
IR On/Off Switch Using Microcontroller
Turning electrical devices ON or OFF using a remote control is a well-established concept, with numerous devices available that perform this function effectively. To create such a device, it is necessary to construct a receiver and a transmitter, as well...
knight Rider
A light computer has been developed that simulates the scanning effect seen in the KITT car from the TV series Knight Rider. The design utilizes a microcontroller, specifically the PIC16F84A, instead of the commonly used CD4017 counter IC. This choice...
Some Voltage Regulator Ciruits for Microcontroller based Projects
A regulated and noise-free power supply voltage is essential for microcontrollers and other components such as amplifiers, filters, and GPS devices. Voltage surges in the supply voltage can permanently damage embedded systems. A voltage regulator must maintain the output voltage...
