Microcontrollers are fun. They are the heart and soul of many everyday appliances. And most of all, microcontrollers are easy to use and to design with, from the point of view of a designer. Figure 2.1 is the block diagram of what a typical modern microcontroller, and especially those in the AVR series, can do. [...]

Lets look at the FTDI series of components for USB Interfacing. The CP210X devices are perfect for generalpurpose USB to RS-232 conversions. When it comes to the Arduino, AVR and PIC hardware platforms, the FTDI FT232R USB UART IC is a better fit. Like the Silicon Laboratories USB interface ICs, the FT232R is a single [...] To date, we have only been able to spot a few YouTube announcements on the Arduino Mega. This image was sourced from the boys and girls over at lusorobotica have been kind enough to supply one of the first images of the Arduino MEGA. The details are still a little sparse, and it did not [...] Also known as “closed feedback” systems, Servo motors come with a control circuit, which senses if motor mechanism is in desired location and if not it continuously corrects an error until motor reaches the proper point. Servo’s usually come in small plastic packages like the following, but keep in mind there is a whole system [...] As a followup to the Teensy AVR appliance article, it appears that we now have an addon that will make using the Teensy as easy to use as an Arduino from the main Arduino IDE. http://www.pjrc.com/teensy/teensyduino.html Teensyduino is a software add-on for the Arduino IDE. It adds the ability to build and run sketches on [...] Before the Arduino came along, Atmel released an AVR based evaluation board called the AVR Butterfly. It was a self-contained, battery-powered demonstration board running the ATMEL AVR ATmega169PV Microcontroller. It included a liquid crystal display (LCD), joystick, speaker, serial port, real-time clock (RTC), internal flash memory, and sensors for temperature and voltage. Newer boards do [...] Due to other commitments, we were away for a while, and we had to put many of our projects on hold for a while, but now we are back. So stay tuned for articles, stories and new projects. And especially look out for our new projects using AVR, PIC and especially the new Audrino platform. |
