With my Grandma’s birthday fast approaching I wanted to put something together that was not too complicated but still sweet enough to make for a cool widget gift. Since fading LEDs never seem to go out of style and grandmas always love to see a heart, putting two and two together here was a no-brainer.

Description This neat little circuit provides 8 LEDs directly driven from the PIC along with a single mode control switch. The firmware elsewhere on this page drives the LEDs with a 5 bit PWM signal providing each of the 8 LED channels with four levels of intensity; off, dim, mid, bright. A number of sequences

Throbbing Apple Logo Sticker This little gizmo adds the iconic “sleeping Mac throb” to an ordinary Apple logo decal. The idea for this came about when passing by the Apple Store in Palo Alto, California late one night. After hours, when the store is “asleep,” the lighted logos out front pulsate just like the power

Aurora 9×18 RGB LED art *** Check out my blog for updated version of this project and more! *** My obsession of LEDs has led me to this. Aurora 9×18 is a thing of beauty (if I can say so myself) – has 162 RGB-LEDs in a circular configuration. The color of each circle is

This project was sent by Electrical Engineer Atanasios Melimopoulos (Copyright (c) June 15, 2007) INTRODUCTION: In-Circuit-Debuggers, as you may already know, have become the PIC’s debugging standard tool for many programmers because it’s easy use and handy interface to the target picplaced- board. They come with MPLAB plug-ins that provides a full rich set of
Hello friends here is a proteus simulation of speed control of DC motor with the help of Pulse width modulation (PWM) control, PWM signals are generated by 8051 microcontroller. As we have discussed earlier that proteus is a really good simulation software for beginners and 8051 is the most basic among all microcontroller so this
