Metal detector circuit
The project demonstration has been successfully completed, with the only remaining task being the final project report due on June 15, which will be integrated with a conference paper. This update marks the last entry in the electronic notebook, although...
Serial LCD Library
This project utilizes a standard Hitachi HD44780 (or compatible) controller chip to operate an LCD display using only two wires. Various shapes and sizes are available, including standard line lengths of 8, 16, 20, 24, 32, and 40 characters in...
hardware aspects of moving message
The moving message will be displayed on the LCD, which will be controlled through a microcontroller. The message will be sent by a computer using RS232. The circuit diagram of the moving message display is shown in this post, and...
repair microcontroller circuit
The difference between these two ICs. A microcontroller is a specialized type of microprocessor designed to be self-sufficient and cost-effective, while a microprocessor is typically intended for general-purpose use, such as in personal computers (PCs). The microcontroller integrates several useful...
Hum Circuit
The kit employs an off-the-shelf microcontroller based on the AtMega328P-PU Arduino, along with a simplified version designed for ease of replication and modification by collaborators and students. This initiative aims to enable the fabrication of simplified microcontrollers for DIY synthetic...
Miniature Real-time Controller
This is my long history the device that controls my home's night light, air-conditioner, etc. The device is a Miniature Real-time Controller. The circuit uses only three chips, a 89C2051, DS275 (or MAX232), and 74LS07 open collector driver. The scheduler...
Game-scoring Display ScreenCircuit
The game-scoring display screen circuit diagram is depicted in the image above. The circuit consists of an add/subtract scoring input circuit, an add/subtract scoring circuit, a counting-decoding display circuit, and a reset circuit.
The game-scoring display circuit is designed to facilitate...
LCD Module
The LCD module is equipped with built-in fonts and can display text by sending the correct commands to the display controller known as HD44780. Comprehensive information regarding the usage of the display can be found in its datasheet. A schematic...
LCD to USB interface
LCD2USB is an open source/open hardware project. The goal of LCD2USB is to connect HD44780 based text LCD displays to various PCs via USB. LCD2USB was meant to be cheap and to be made of easily available parts. It is...
