Atmega168 TV-B-Gone

Yes, I know what you are thinking: "oh no, please not another TVBGone..." Anyway, this instructable is for the newbies as me which are still experimenting with Arduino, and prefer to program an Atmega168 in Arduino than an AtTyny85 with other methods. This circuit is based on Mitch Altman's TVBGone and on Ken Shirriff's blog where the software has been modified to match Arduino IC. I then decided to move th ...

Interfacing 16X2 LCD to AVR Microcontroller

Well this is not different from the way interfacing the LCD to 8051 or PIC microcontroller. The crystal oscillator will provide the clock to the microcontroller. The capacitors connected to the crystal will act as filters and help the crystal to resonate and oscillates to its parallel resonate mode.  The potentiometer which is connected to the pin 3 and pin2 of LCD will help to adjust the contrast of the LC ...
