The RW line is the "Read/Write" control line. When RW is low (0), the information on the data bus is being written to the LCD. When RW is high (1), the program is effectively querying (or reading) the LCD. Only one instruction ("Get LCD status") is a read.... -
The Atmel AVR series are very good microcontrollers with quite a rich instruction set, rich enough that lots of folks have good compilers for them so we don`t have to learn their assembler. A very rich compiler available is the BASCOM/AVR compiler from MCS.... -

This simple AVR Programmer able to transfer hex programs to mostATMEL AVR microcontrollers. It is more reliable than most other simpleAVR programmers available out there and can be built in very shortamount of time. This Programmer support the AVR.... -
This article describes the Gadgets Gizmos and Arduino (ATMega328). The content is very simple, very helpful. Components in this article can help you understand better understanding of this article. For example, in this article, you can go to find and buy.... -
It`s a single integrated circuit with EEPROM, Ram, Analog to Digital converter, a lot of digital input and output lines, timers, UART for RS 232 communication and many other things. The best is however that a complete programming environment is available.... -
ISP is a way to serially program your microcontroller, while it resides in its place, in other words, without removing the chip from your board. Whether you`re just starting in the ATMEL microcontrollers, or you`re familiar with it, ISP (In System.... -
Wire the circuit diagram shown here on a bread board. The choice of V type of AVR is important. For example Tiny13V is very appropriate for such an ex.... -

The Morse Beepy is a circuit I designed to be simple and cheap enough for kids and adults to use as a first soldering project, but powerful enough that they could have fun with it. In fifteen minutes, it can be soldered together and programmed to beep and.... -
Atmel`s application note AVR109 describes a bootloader that uses the UART to communicate FLASH programming instructions. They also provide some sample code in C that allows the programming of FLASH, EEPROM, and lock bits. Note that the AVR109 bootloader does.... -
Why would you want to use the Arduino library with another IDE It helps organize your code (especially for large projects), is easier to implement other code not written specifically for Arduino and can be a gateway to more powerful programming tools and.... -
The line is purposefully not straight, to see how it would do with zig-zags and splits, as are normal for the Chibots advanced line-following contest. The AVRcam is a small, real-time image processing engine capable of tracking colorful objects. The system.... -
This is my first AVR-project on this page. The DiSEqC-Tester allows to test DiSEqC-switches that uses 1. 0 or 1. 1 protocols. (DiSEqC-Switches with 2. 0 and 2. 1 protocol have backwards compatibility with 1. 0 & 1. 1 respectively and also may be tested). The.... -
It is important to layout your PCB correctly to allow trouble free In System Programming of AVR microcontrollers. This guide covers the usual problems that are encountered and typical AVR ISP circuit schematics. This guide covers Serial Programming, which is.... -
