On this page you will find the technical information for building the electronic control unit of my homemade film processing machine. To see the rest of this film developing apparatus, look at the relevant article in the photography section of this site. Developing a color film is a simple procedure of putting it in a […]
Here you will see how easily we can make Digital frequency meter by PIC microcontroller using timer 1. To make this project we need clear idea on timer 1 module of PIC16F877 microcontroller. We need to know how we can configure timer 1 module to do our desire work. For that I suggest please refer […]
Microcontroller based electronic circuit diagrams, Electronic circuit diagrams / circuit schematics. if you would like general assistance with a specific design question you may like to try the electrical engineering. Interfacing lcd modules pic microcontrollers., In this tutorial we will learn how we can use lcd modules with microchip pic microcontrollers. here i will […]
This post provides the internal EEPROM reading and writing code for PIC16F84A microcontroller. As we know[1], PIC16F84A microcontroller has 64 bytes of built in EEPROM data space with an address range of 0x00 to 0x3F. This code is written in C language using MPLAB with HI-TECH C compiler. You can download this code from the ‘Downloads‘ section at the […]
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. […]
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 […]
This PIC16F877 microcontroller tutorial answers the question, ” How to use timer0 of PIC16F877 and how to handle its interrupts? ” Using PIC16 simulator (Proteus) you can verify this PIC timer0 code and change it according to your needs. This code is written in C language using MPLAB with HI-TECH C compiler. You can download this […]
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 […]
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 […]
The servo motor is widely used in model hobbyist such as airplane R/C model for moving the rudder, ailerons, elevators and acceleration control or in the car R/C model for steering and acceleration control. In this tutorial we will learn how to control the servo motor as well as the simple close loop control algorithm […]
