Introduction: An accelerometer is an electromechanical device which measures acceleration. A measure is normally in G-forces. One G-force is equivalent to 9.8 meters per second squared. Accelerometer is widely used in many devices such as mobiles, Unmanned Aerial Vehicles, cars etc. They are mainly used for determining tilt by measuring amount of acceleration due… Read More Accelerometer Basics
MICROCONTROLLER A highly integrated chip that contains all the components comprising a controller. Typically this includes a CPU, RAM, some form of ROM, I/O ports, and timers. Unlike a general-purpose computer, which also includes all of these components, a microcontroller is designed for a very specific task — to control a particular system. As a… Read More PIC16F877A Microcontroller : Basics
THEORY Pulse width modulation (PWM) is a method of controlling the amount of power provided to an motor or any other load connected. The fraction of the period for which the signal is high is known as the duty cycle. The average DC value of the signal can be varied by varying the duty cycle.With… Read More Pulse Width Modulation Using PIC16F877A
Digital thermometer is used for determining room temperature. It is basic project for beginners to understand functions of different pins of PIC16F877A.It is made by using analog-to-digital conversion(ADC) function in PIC16F877A & seven segment display(SSDs) using LM35 as temperature sensor. Sensors are widely used for temperature measurement but LM35 series is precision Integrated Circuit… Read More DIGITAL THERMOMETER USING LM35
