In this projects 8 different colors are displayed with the use of a RGB LED. The microcontroller that is used is the ATMega8.
This board is a development board on which you can build your projects. It is suited for educational use, experiments or prototyping. The board uses the ATTiny2313 microcontroller with a 20Mhz clock. The board contains the ISP 10-pin connector for in circuit serial programming. It has also a push button reset switch. It has 15 digital I/O ports with 4 PWM output channels.
The ATMega328 board is a microcontroller board based on the ATmega328, The board contains everything needed to support the microcontroller. The board need 5VDC to power it. Simply connect the power connector to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. You can program it with the ICSP connection. The ATMega microcontroller boards can be programmed with a serial port programmer, parallel port programmer or USB port programmer.
With this circuit you can control two unipolair stepper motors in full step mode via the RS232 serial port of your PC. A terminal program such as Hyperterminal can be used to control the stepper motors. The stepper motors can be driven one at a time.
