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...

Jet

The microcontroller is able to make about 7000 complete line-following decisions per second, which is almost 7 decisions per millimeter when the robot is going full speed. By upping the clock, unrolling loops, and removing my wireless debugging and extraneous...

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...

87C51 Selling Leads

This circuit utilizes an 87C57 microcontroller along with several peripherals to convert X-10 power-line carrier-code formats from a personal computer for use with an X-10 power-line interface in a home control system. Software details can be found in the reference....

Multitasking Pins

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 multiple functions. One approach is to exploit the...

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...

MCU controlled Bluetooth automation

The microcontroller used is 0822 zilog encore! 8k series (soic,28pin) as shown on the figure. Is a programmable microcontroller, the functions used are the GPIO and the UART of the chip. GPIO is used on led indicators, and the UART...

Microcontroller interfacing with RS 232

Standard serial interfacing of a microcontroller (TTL) with a PC or any RS232C standard device requires a TTL to RS232 level converter. A MAX232 is used for this purpose. It provides a 2-channel RS232C port and requires external 10µF capacitors. The...
