Eight-digit-microprocessor-display
The display interface utilizes the ICM7218A/B in conjunction with an 8048 family microcontroller. An 8-bit data bus (DBO/DB7-IDO/ID7) facilitates the transfer of control and data information to the 7218 display interface during successive WRITE pulses. The mode input pins on...
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...
synchronizing fireflies ng
This is a remake of the fireflies project that was created a year ago. The concept revolves around the emergence of patterns, particularly the synchronization of hundreds or thousands of fireflies. Initially, they flash randomly, but over time, influenced by...
Microcontroller Relay Driver and Interface
Many microcontroller designs typically integrate various interfacing methods. A microcontroller (µC) system can be viewed as a system that reads from inputs.
Microcontroller systems are versatile platforms that facilitate the integration of multiple interfacing methods to interact with various peripherals and...
DC motor driver for DCMP(AVR-008)
A microcontroller is used to control various types of DC motors, including permanent magnet DC motors, DC servo motors, and stepper motors. This project utilizes the AVR-008 microcontroller from Circuits-Home, which is frequently referred to as the 3-in-1 driver motor...
Unidirectional motion sensor
This circuit detects an object passing in one direction while ignoring it in the opposite direction. Two sensors determine the direction of movement. When an object approaches, it first blocks the light to phototransistor Q1 or Q2, depending on the...
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...
Password(code) Based Digital Locking System Using Microcontroller 89C52/89S52
Upon entering the password, the application, in this case "LED," will illuminate. In this digital locking system project, the interfacing of a keypad and a 16x2 LCD with a microcontroller will be explored, along with the accompanying code. This project...
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...
