This is versatile development board for AVR microcontrollers ATmega48/88/168. It is good for testing and debugging embedded programs. It has many built-in peripheries connected to microcontroller so you can use them without soldering. ATmega microcontrollers are produced by ATMEL and they include a lot of features: I/O, Timers, PWM generators, ADC, RS232, TWI, SPI, Analog Comparator, Oscillator, EEPROM These microcontrollers are very versatile, easy to program and easy to use. This is the reason why I like these microcontrollers and why I decided to make development board for them.

Snaky is built around a powerful ATMEGA88 AVR microcontroller from Atmel, twelve miniature servo-motors and a few other components. On the software side the most CPU intensive section is the PWM generation, as 12 PWM signals are generated with a resolution of 20μs and a quite high pulse refresh rate. To achieve this target an innovative firmware architecture is implemented, managing two PWM channels at a time.

This precise, user-friendly ATmega88 based talking calculator operates with real numbers. It features the four basic operations (addition, subtraction, multiplication, and division) and several useful functions (e.g., change of sign (+/–), inverse (1/x), add with memory (M+), and read from memory (MR). Then after the calculator operates it displays the result on the LCD screen and also has the option to play the results via its speech engine.

Motion Sensor are often needed when working on security system projects or with robotics. For example you could embed this project into your robot and write a code that will allow the robot to do various actions when motion is detected or you could embed this project into a security system that will record video, when motion is detected. The project is based on ATmega88 microcontroller and can detect movement at 30 frames per second.
