Microcontroller atmega8 combines functionality, compactness, and relatively low price. These qualities have given the widest dissemination ATmega8 among professional and amateur structures.
The microcontroller has a wide range of modules and can be used in a large number of devices for different purposes, from timers, dimmers, automation systems to generators of special signals, video decoders and standard RC5.
The microcontroller atmega8 has two full port with 8 bits. The presence in the atmega8 analog-to-digital converter enables to measure parameters such as voltage, current, capacitance. This allows you to develop on the basis of a complete microcontroller multimeter.
Also atmega8 has a UART port for receiving and transmitting data TTL level. Port for the protocol TWI (the opportunity to realize a software I2C ). By I2C to ATmega8 can connect a variety of devices:
- - external EEPROM memory series 24cXX,
- - matches indicators and graphical displays,
- - volume control, resistance, and much more.
