µP-Controlled Oscillator Delivers Rock-Bottom Distortion
Function generators are essential in the design, testing, and operation of encoders, modulators, demodulators, and measurement instruments. This document presents an economical method to construct a bus-controlled sinewave oscillator that exhibits exceptionally low distortion. The circuit produces a sinusoidal output...
Sensors and Sensing
The ability to perceive colors, shapes, distances, spatial relationships, motion, and connectivity is integral to human experience and cognition. This perceptual framework enables interpretation of sensory information through a complex model of the environment. Robots, however, lack such inherent models...
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...
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...
Driving circuit schematic
The driving circuit depicted in Figure 18-12 consists of a connection between the driving portion, the microcontroller, and the air conditioning operation components of the bridge. The microcontroller's digital signal levels from ports P4.0 to P4.3 (approximately 12 feet) and...
POWER LINE MODEM FOR COMPUTER CONTROL
This circuit employs 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.

The frame memory circuit
A digital signal processing circuit that operates in conjunction with a memory system for temporarily storing image data. The DPTVT-3D/MV digital processing chip requires four KM416S102 memory units, each providing 16 MB of digital memory. The circuit structure is depicted...
10 or more switches using a microcontroller
There are several methods to read multiple switch inputs using a reduced number of microcontroller unit (MCU) pins. One approach involves using an analog MCU pin to read multiple switches by assigning a unique voltage to each switch through a...
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...
