This project is aimed to design a ‘Sleep and Wake-up Assistant’. Different from a normal alarm clocks which can only make noise, this alarm clock is designed to wake up a person in a comfortable and effective way by involving sound, light stimulation, motion detection and vibration. The functions of this alarm system are: (
This post provides the code to make an LED blink using PIC16F877 microcontroller. This code is written in C language using MPLAB with HI-TECH C compiler. This code is intended to be the first step in learning how to use PIC16F877 microcontroller in your projects. You can download this code from the ‘Downloads‘ section at the bottom

This project drives a number of LEDs via a very clever circuit. There are 3 ways to dive a LED from an output of a micro. The simplest is called “dump.” This is where the LED is connected directly to the output via a resistor and when the output is HIGH, the LED illuminates. But

In this tutorial we will learn How to Blink an LED with PIC Microcontroller using MPAB XC8 Compiler. Recently Microchip released a series of development tools including MPLAB X IDE and MPAB XC Compilers. MPLAB X IDE is a software that runs on a computer intended to develop applications for Microchip’s Microcontrollers and Digital Signal

Pulse Width Modulation (PWM) is a technique in which the width of a pulse is modulated keeping the time period of the wave constant. One cycle has a fixed time period called ‘Period’ and a varying on time called ‘Duty cycle’. The entire wave can have two voltages levels either logic 0 or logic 1.

Description This project is a multi-function LED bike (cycle) light using 3 LEDs. It is based on a PIC10F200 baseline microcontroller, running from a supply voltage of 2 to 5 volts. In standby mode it consumes a current of less than 1µA making it perfect for battery powered operation. It uses three individually driven high

Here’s the updated firmware for my Universal High-Power LED Driver. This version has on-board current set up function, so you can change the drive current without re-programming the PIC microcontroller. You can either download the ZIP file containing the while project, or just the HEX file. After upgrading your firmware, you can change the drive current of the

This is a little night-light that comes on when it gets dark, to illuminate dark rooms or hallways. I’m sure you can buy these cheaply ready made but it’s more fun to make your own, and this way it can be customised exactly how you want it. Power efficiency The unit is very efficient –

In the simple tutorial we are going to blink few simple led with PIC18F microcontroller, using an external 20MHz crystal oscillator and the ‘__Delay ()’ function of XC8 Compiler. Most of the previous tutorials here dealt with internal oscillator of pic18F4550 where mostly the delays were generated with simple for loops. However those who wish
