Dear friends,
On
this site, you will find many circuits based on AVR
microcontrollers (μC) from Atmel. I will be adding more circuits,
because micro controllers, are used in a lot of applications.
The
purpose of my site is to teach all of you that want to learn about
electronics, to work with these little powerful things. I believe you
will be helped a lot by
the source code that I present in my web site.
Today, microcontrollersare very advanced. All
microControllers contain FLASH memory, USART, RAM, EEPROM, TWI and
many more features, all in one chip at very low cost.
Happy reading,
Vassilis Serasidis
