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

We have seen many projects using a set of LEDs to produce words “in the air,” but none have the clever feature we have included. Most of the projects are “shaken in the air” and produce messages that are “all over the place.” But if the words are jumping they are difficult to read. Our

Introduction By measuring brain activity using electrodes and an amplifier circuit, electroencephalograms (EEGs) are at the intersection of electrical engineering and neuroscience. By using signal processing techniques, we can examine the effects of external stimulation, such as music and meditation, on brain waves. We primarily examined alpha and beta brain waves in our EEG. While
