IR Communications Used in IrDA, and Remote controls Short Range Requires two devices to be in line of sight. In this tutorial we will learn how to practically implement a wireless link between two MCUs. What is a RF Module ? A RF Module is a small circuit pre built and tested. As you can see they have very low pin count. TX Antenna Vcc (Positive Supply) DATA (Data Input) GND RX Antenna GND GND Vcc (Positive Supply) Vcc (Positive Supply) DATA DATA GND So you just need to apply power and fit an antenna and its ready to work.

AVR projects and AVR Butterfly gcc port by Martin THOMAS G.d.W. SS2010 FHFFM You may like to visit my ARM-Projects page too (projects and information for NXP LPC2000, Atmel AT91SAM7, STmicro STR7, STM32, LMI LM3S and other controllers with an ARM-core). Available Projects and Information (Content) "Last updated" may be just additional information not always a new version of a software-package. AVR Butterfly Application code port to avr-gcc Introduction The AVR Butterfly (ATAVRBFLY) made by ATMEL comes with a preloaded application. For german readers: Der Quellcode der auf dem AVR-Butterfly installierten Applikation wird von ATMEL für den IAR C-Compiler zum Download bereitgestellt. Even if you do not own an AVR Butterfly you may find usefull information in the BF application code for general ATMEL AVR development tasks. From the gcc-port of the application code some methodes how to convert IAR-code to avr-gcc/avr-libc-code can be learned. Butterfly gcc-port history Software 2.Oct.2003 - 4.

Datasheet catalog for integrated circuits, diodes, triacs, and other semiconductors, view Getting Started with the TIVA™ C Series TM4C123G LaunchPad Version 1.22 November 2013 Labs are based on CCS 5.5 and TivaWare 1.1 Preface The intent of this workshop is to be a place where a person with a few C skills and some microcontroller experience can familiarize themself with the Tiva C Series parts, Code Composer Studio, TivaWare for C Series and the process of programming these microcontrollers. If you lack C programming skills, there are many courses on the Internet where you can gain them ... that knowledge can form the basis for a rewarding career. If you are migrating from earlier Stellaris devices, please refer to this document for more information. The labs in this workshop (with the exception of Chapter 15's PWM lab) will also work perfectly well on the Stellaris LM4F120 LaunchPad ... no changes are required. Introduction The Getting Started with the TIVA C Series TM4C123G LaunchPad Workshop is an in-depth, hands-on introduction into Tiva C Series basics including: The workshop labs are constructed using TivaWare™.

Electronic Projects For Beginners I made a guide for those people who are still starting with their electronics hobby. I started connecting wires, batteries, bulbs, buzzers and motors when I was 4 years old . Now that I am 13 years old, I now have a good amount of experience to build complicated electronic circuits. It took me hours to finish making this guide since there is no software editor in the Sibmit>Guide in the "Submit Instructable Section" I had to type every word and picture using HTML codes which I learned from school. These are my all time favorite projects in instructables, I find them simple and easy to make.
