Dear friends,
On
this site, you will find many circuits based on AVR
microControllers (μC) from Atmel. I will increase the number of the circuits,
because microControllers, are used in a lot of applications.
The
purpose of my site is to learn all of you, that you want to follow the
technology of electronics, to work with this little powerful things
that are called microControllers. I believe you will be helped a lot by
the source codes that I present in my web site.
The
technology of microControllers now is very high. All
microControllers contain FLASH memory, USART, RAM, EEPROM, TWI and
many more features, all-in-one chip at very low price.
Have a good reading,
Vassilis Serasidis
