Cooper Bills (csb88) and Anish Borkar (ab673)

Introduction The Handy Lab Buddy is a tool every ECE should have. The four features of this tool include a talking voltmeter, logic probe, voltage averager, and frequency measurer. As a cheap and accurate device that outputs whatever being measured through speakers, it's one of its kind and an essential tool for lab work. Summary Have you ever tried to debug a circuit and just wished your voltmeter would ta ...

PIC16F84A MemoSound Game

Game rules You will have to memorize a melody, made of up to 62 steps. A step is one of the four tones available in the game system. In order to help you, each tone is associated to a color LED (yellow, green, orange, red) which lights each time the tone is played. The game system plays the melody, then you have to repeat it correctly by pressing the button of the tone's LED. At the beginning, the melody ha ...

Dual 4-digit seven segment LED display with SPI interface using PIC12F

This project is an extension of my previous MAX7219 based SPI seven segment LED display module. The new display features eight 7-segment displays arranged in two rows of four digits. The on-board MAX7219 driver enables you to easily add eight 7-segment LED displays to your project using only 3 I/O pins of microcontroller. The major advantage of using this board is the time-division multiplexing operations r ...

5 LED CUBE Controller for PIC16F688

Circuit Description The LED cube is made up from 125 LEDs arranged into 5 layers of 25 LEDs each.  The display itself is multiplexed so instead of requiring 125 connections it requires one to each of the five layers and 25 to each LED in a layer making a total of 30.  The cube is refreshed by a software interrupt routine with each layer active for 2ms, so the entire cube is refreshed every 10mS (100Hz). Thi ...

Complete Intro To PIC’s – Make an LED Flash Video

As the title suggests, this guide is targeted for those who are new to the world of PIC microcontrollers. I cover the basics from hardware to software along with programming the device and a few hints along the way. I do assume a little bit of electronics knowledge - eg, reading circuit diagrams - I'm guessing if someone has the knowledge to Google "Intro To PIC's" then they know something about basic elect ...

Serial Addressable RGB PWM LED Driver using PIC16F628A

Overview Ever since I made the serial controlled RGB LED PWM driver I've had many requests for an addressable driver.  Well I've finally got round to producing one.  The code is now completed and tested and the prototype boards are fully working. The design process behind this project was to enable anyone with a bit of electronics knowledge to build an array of cheap RGB LED drivers that they can control fr ...

Arduino powered temperature sensing RGB LED nightlight using PICaxe

About a year ago I started on a project to make a temperature controlled nightlight. I was inspired by seeing these lovely LED lamps styled as mushrooms growing out of pieces of wood. Those mushrooms were made out of glass, which was somewhat beyond my skills. However I then saw some had used translucent sculpey to make mushroom nightlights on instructables. So with that discovery it seemed like it would be ...
