AC Voltage measurement using PIC16F877A microcontroller

AC Voltage measurement using PIC16F877A microcontroller

Note: Microcontroller  PIC16F73  can be used instead of pic16f877a. This time we will see how to measure AC voltage parameters with the help of micro-controller. First we will know about AC voltage parameters, then we will do the whole work step by step. What is AC(Alternating Current): “In alternating current (AC, also ac), the flow of electric charge periodically reverses direction.

Transmit & Receive Infrared Signals With Your PC Serial Port using PIC12F508

We no longer manufacture or sell the original Air-Byte IR transceiver, so we’re releasing the code & circuit design here for hobbyists and students looking to build a simple IR transceiver. Note that the parts used here are not critical. I.E. the NPN darlington transistor driving the infrared LEDs, PNP transistor used for inverting the

LEARN HARDWARE FIRMWARE AND SOFTWARE DESIGN BRIEF DESCRIPTION

LEARN HARDWARE FIRMWARE AND SOFTWARE DESIGN – BRIEF DESCRIPTION

Edition 5 of LHFSD [ISBN 978 606 92185 32] has been specifically designed to become an educational/pedagogical manual for teachers, instructors, and also for ordinary citizens. Have no fear, dear readers: LHFSD is still addressed to beginners, since EVERYTHING starts from a white page, and then things are developed/explained only gradually [and logically], step by

Using Serial Peripheral Interface SPI with Microchip PIC18 Families Microcontroller

Using Serial Peripheral Interface (SPI) with Microchip PIC18 Families Microcontroller

The Serial Peripheral Interface (SPI) is one of the popular embedded serial communications widely supported by many of today’s chip manufacture and it considered as one of the fastest serial data transfer interface for the embedded system. Because of its special in/out register configuration, the SPI master device could transfer its data and at the
