With recent advances in semiconductor technology, the maximum luminous intensity of red l.e.d.s has increased to several candelas. Now consider that human flesh is translucent to red light. Combine these two facts, and we have the basis for this project. The average facial cheek has a thickness of between one and two centimetres, and this makes it possible to “backlight” a cheek from the gums with a high intensity l.e.d., causing it to glow in the subdued light of a Christmas party or disco etc. The slimline circuit featured in this article is slipped between the gums and cheek, and is activated by the presence of saliva. Just think of the attention you will attract with flashing cheeks!

  • Programming-8Bit-PIC
    Foreword Embedded microcontrollers are everywhere today. In the average household you will find them far beyond the obvious places like cell phones, calculators, and MP3 players. Hardly any new appliance arrives in the home without at least one controller and, most likely, there will be several—one microcontroller for the user interface (buttons and display), another to control the motor, and perhaps even an overall system manager. This applies whether the appliance in question is a washing machine, garage door opener, curling iron, or toothbrush. If the product uses a rechargeable battery, modern high density battery chemistries require intelligent chargers. A decade ago, there were significant barriers to learning how to use microcontrollers. The cheapest programmer was about a hundred dollars and application development required both erasable windowed parts—which cost about ten times the price of the one time programmable (OTP) version—and a UV Eraser to erase the windowed part. Debugging tools were the realm of professionals alone. Now most microcontrollers use Flash-based program memory that is electrically erasable. This means the device can be reprogrammed in the circuit—no UV eraser required and no special packages needed for development. The total cost to get started today is about twenty-five dollars which buys a PICkit™ 2 Starter Kit, providing programming and debugging for many Microchip Technology Inc. MCUs. Microchip Technology has always offered a free Integrated Development Environment (IDE) including an assembler and a simulator. It has never been less expensive to get started with embedded microcontrollers than it is today. While MPLAB® includes the assembler for free, assembly code is more cumbersome to write, in the first place, and also more difficult to maintain.

  • Introduction to Microcontroller Programming
    Page 2 Welcome to the course! The course contains a series of programming exercises, (part 1) supported by background information for reference, (parts 2 to 6). Part 1 - Programming Exercises - p.4 Part 2 - Using E-Blocks - p.29 Part 3 - Introduction to Flowcode 7 - p.37 Part 4 - Flowcode 7 - Your first program - p.48 Part 5 - Flowcode 7 - Worked Examples - p.55 Part 6 - Introduction to Microcontrollers - p.84 Part 7 - Course Rationale - p.106 Your route through it: Broadly speaking, there are two types of student: The experienced programmer: probably begins with the ‘Programming Exercises’, (part 1), referring back to the information in the other sections, as and when needed. After all, programmers only read the manual when they get stuck! Nevertheless, before starting an exercise, you should familiarise yourself with the reference section(s) so that you know where to look for help should you get stuck! The less confident user: concentrates first on the reference material and the worked examples and then attempts the exercises. Copyright © 2016 Matrix Technology Solutions Limited www.matrixtsl.com Page 3 Before you start: ‘Flowcode 7’ works with a range of microcontrollers, including PIC, Arduino and ARM. For simplicity, this course focuses on PIC microcontrollers. It also includes information for the Arduino user. ‘Flowcode 7’ itself is microcontroller neutral - it presents virtually the same user interface regardless of the microcontroller used. The differences are in the hardware and the way the program is downloaded and tested. For PIC users, most of the exercises use the E-blocks EB006 v9 Multiprogrammer and the EB083 Combo board.

  • Logic, Drive Control, and User Interface Integration of a Multidiscipline Kinetic Sculpture
    Logic, Drive Control, and User Interface Integration of a Multidiscipline Kinetic Sculpture Submitted By Jason D. Adrian IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR AN UNDERGRADUATE HONORS THESIS WITH A BACHELOR OF SCIENCE IN COMPUTER ENGINEERING School of Engineering Tufts University Medford, Massachusetts May 2004 Signature of Author: Committee: Jason D. Adrian Professor Joseph P. Noonan Dept. of Electrical and Computer Engineering Tufts University Committee: Committee Chair: Professor Chris Rogers Professor Chorng Hwa Chang Department of Mechanical Engineering Dept. of Electrical and Computer Engineering Tufts University Tufts University © Copyright 2004, by Jason Adrian Abstract Five diverse disciplines including mechanical, electrical, and computer engineering in tandem with human factors and child development helped create an interactive learning device called the kinetic sculpture. The kinetic sculpture consists of five engaging user interfaces that control the actions inside a Rube Goldberg-like device. The sculpture actions are controlled by DC, AC, and stepper motors along with solenoids to control the path of the ball in the sculpture. N-channel and P-channel MOSFETs were used extensively to control the motors and electronic components. The heart of the modular input devices is a PIC microcontroller which interfaces with both sensor inputs and LED output displays. The electrical and mechanical components together formed a unique and interactive learning device for elementary school children. i Table of Contents INTRODUCTION.......................................................................................................................................
