Industrial Building Automation System (IBAS) - 4
The two optical sensors will provide a count of individuals to the microcontroller, which will relay this value to MCU-II. The microcontroller will detect the entrance of any person through high-to-low pulse transitions on input pins A3 and A4.
The circuit...
Multitasking Pins circuit
It is entirely logical that low-cost miniature microcontrollers have fewer pins than their larger counterparts, sometimes too few. Consideration has been given to how to economize on pins by making them perform the work of several. It was noted that...
Perfect Pitch Circuit
Perfect Pitch, which is based on the 8751 microprocessor, is an affordable and straightforward instrument tuner and frequency counter that features a built-in headphone amplifier and a visual metronome. Perfect Pitch converts the audio signal from an instrument into a...
Microcontroller-based automatic night light circuit
While discussing an all-linear automatic night light circuit, it was mentioned that an MCU-based Automatic Night Light Controller (ANLC) was being tested. The firmware has been tweaked since then. Recently, the sensor was installed outdoors and connected to control 220VAC...
home security system
The fundamental design of this project employs an Atmel AT89S8252-24PC Microcontroller, which features 2KB of EEPROM for runtime data storage. An ADC0838CCN analog-to-digital converter will be utilized to process up to eight inputs from sensor devices, including passive infrared sensors...
graphical LCDs with a microcontroller
How can graphical LCDs be controlled using a microcontroller? Is there any datasheet available?
Graphical LCDs (Liquid Crystal Displays) are widely used in various electronic applications for displaying complex graphics and text. To control these displays with a microcontroller, several steps...
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...
Microcontroller and Motor Driver Circuit Board
Efforts were made to minimize the number of wire jumpers on this board, but space constraints arose due to the integration of the microcontroller and motor driver on a single board. The design would have been cleaner without the inclusion...
analog to digital converter adc0804
The circuit involves 8-bit, microprocessor-compatible analog-to-digital converters (A/D converters). It utilizes the ADC0804 chip for converting analog signals to digital form, in conjunction with an AT89C2051 microcontroller. The ADC0802 family consists of CMOS 8-bit, successive-approximation A/D converters that employ a...
