Lcd circuit | Next Electronics

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...

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...

Microcontroller

The gap between TTL (Transistor-Transistor Logic) devices and personal computers can be effectively bridged with modern microcontrollers. These microcontrollers not only incorporate a central processing unit (CPU) but also include program and data memory, EEPROM, input/output (I/O) ports, timers, and...

High Resolution Digital Weigh-scale Design Using Z8 Encore! ?® Microcontrollers

The SP6691 circuit is designed to provide a high output voltage using a lower voltage boost regulator by incorporating a charge pump circuit. This configuration can convert a standard 30V boost regulator into a 60V boost regulator if necessary. Testing...

integrated circuit Improving absolute precision of ADC to balance battery voltage

Utilize a high-performance microcontroller (Piccolo TMS320F28035, 12-bit resolution, +/- 4 LSB offset, +/- 60 LSB gain) to measure the voltage across stacked battery cells and control related analog electronics for charge equalization. The microcontroller will also save data in EEPROM...

Water Level controller

The microcontroller-based water level controller and motor protector manages the on and off states of the motor based on the water level in the overhead tank (OHT). It regulates the tank's water level through a microcontroller, thereby providing automatic protection...

Low Resource Microcontroller 3 Phase BLDC Motor Speed Controller

This article discusses a minimal resource microcontroller implementation for a three-phase Brushless DC (BLDC) motor, focusing on a closed-loop speed motor controller application based on a Microchip PIC12 device. It demonstrates how minimization techniques can reduce the number of I/O...

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...

Talking Yoda head

The talking Yoda head consists of a Yoda mask and a microcontroller system to achieve the desired operation/effect. The basic operation of the project was specified as follows: The head was to be placed inside a closed box. Upon opening...
