  • Programming-8Bit-PIC

    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.

Sat Making photograms using UV from the atmosphere. Colour tinting prints. Preparing digital negatives on a computer. Making contact prints using an Sun industrial UV exposure machine. The Cyanotype​ method is an incredibly versatile, simple and fun process to learn. The Cyanotype was invented by Sir John Henry Herschel in1841. This early photographic process produces distinctive and striking Prussian blue images which can also be toned in various other colours. Simple and economic, it remained in use well into the twentieth century as a means of reproducing architectural and engineering drawings as Blueprints. In more recent times, the Cyanotype has been rediscovered by contemporary artists. Also sometimes known as sun printing, the Cyanophyte process is one you can easily learn to do in a weekend. It offers a perfect introduction to alternative and traditional photographic processes and to the use of computers to produce photographic negatives for such processes. The course takes place in the Print Studio and also utilises the Digital Suite at the Art Academy. Both facilities offer a much wider programme of evening, weekend and daytime courses throughout the year. Please refer to our website for full terms and conditions: Mermaid Court, 165A Borough High Street, London SE1 1HR www.artacademy.org.uk/terms-conditions/ 020 7701 2880 The cyanotype process is simple, non-toxic and can be adapted and incorporated into a range of other printmaking techniques such as photo-etching and mono-printing.

Faculty of Technical, Vocational Education & Skill Training Notes B.Voc. theatre, Stagecraft, Film Production & Media Technology Subject : - Basic Audio Video Production Unit 1 What is Cinematography ? Cinematography is the art of visual storytelling. Anyone can set a camera on a tripod and hit record, but the artistry of cinematography comes in controlling what the viewer sees (or doesn’t see) and how the image is presented. Film is a visual me- dium, and the best-shot films are ones where you can tell what’s going on without hearing any of the dialogue. With some basic knowledge of composition and scene construction, you can plan scenes using this visual language. Learn how different shots work together to form a clear, cohesive narrative and how to compose each shot in a way that is visually pleasing for the viewer. Understanding these simple rules will help make your films more thrilling and engaging. Basic Rules of Composition There are some simple cinematography techniques that will have a great impact in making your videos look more professional. The Rule of Thirds is a technique of dividing the frame up into a 3x3 grid, splitting your frame into nine boxes. Our natural impulse is to put our subject dead center, but a centered subject will look like they’re caught in a spotlight, and by dropping them in the center of the frame, it gives them nowhere to go. Instead, by positioning your action in any of the four vertices where those nine boxes meet, you create a balance in your composition that feels more natural.
