Temperature controlled fan using PIC 16F877A

You might have come across several applications where we need to control a specific device based on analog parameter. This Embedded system works in a similar concept where we are about to control the speed of a DC motor using based on the external temperature. The rise in temperature will result in increase in speed of the motor and vice versa. These type of Temperature controlled fan systems can generally ...

Matrix Keypad interfacing with PIC microcontroller.

Matrix keypads are very useful when designing certain systems which needs user input. These keypads are constructed by arranging push button switches in rows and columns as shown in Fig.1. Scanning keypad to detect pressed keys involves several steps and there are several methods to achieve this. The method presented here is capable of detecting more that one key press at time and encode that information in ...

Free programming software for various of the MicroChip PIC series of micro-controllers by Nigel Goodwin.

Following the name change to WinPicProg I've now bought the domain name winpicprog.co.uk so all future updates will be under this address, with links from my old pages. I'm happy to try and help with any problems people have, either via email or (preferably) via the new PHPBB support forum, where other users will be able to take advantage of the answers. I've added an FAQ page to the support forum, and the ...

How to Wire a PIC Microcontroller?

I'm completely new to the world of PIC Microcontrollers and electrical engineering so please go easy Anyway, I managed to program my PIC 16f627 to turn on three LEDs when push button (trigger button) is pressed and start a shut down sequence (basically each LED toggles off one after another with a 5 second delay in between) when another pushbutton is pressed (reset button). I've been testing this on a Velle ...

Book: PIC Microcontrollers

Appendix B: Examples The purpose of this chapter is to provide basic information about microcontrollers that one needs to know in order to be able to use them successfully in practice. This chapter, therefore, does not contain any super interesting program or device schematic with amazing solutions. Instead, the following examples are more proof that program writing is neither a privilege nor a talent issue ...

Execute Open-Source Code in a PIC Microcontroller Using the MPLAB IDE

The PIC32 single-board computer is a de facto standard tool for developing microcomputer applications within the hobbyist and educational communities. It provides an open-source hardware (OSH) environment based on a simple microcontroller board, as well as an open-source (OS) development environment for writing software for the board. Here’s an approach that enables PIC32 code to be configured for execution ...

Simple Digital Current Meter (DCM) using PIC microcontroller (Schematic + code + Proteus simulation)

This post would provide a working example of how to make a simple Current Meter (DCM) using 16bit PIC microcontroller and a series shunt resistance. We have very precise ammeter current measurement with a 10bit ADC and with a tolerance of ±10mA. You may download code and Proteus Simulation from the download section at the bottom of this post. I am using MPLAB X IDE, C30 Compiler and Proteus Simulation on v8 ...
