hi friends!

i have to do a project... its sliding gate opener's control panel...

i have 7 inputs... pushbuttons, 4 relays +2 triacs for speed control of ac motor, 6 user inputs via potentiometers. dip sw with 2 sw ... serial communication and reset sw...

so which avr mcu should i select... cost consideration+functions... i had used atmega8 previously...

cost is a factor... triacs also need zero crossing detection for which compaartor would help but its optional to use zero crossing for me...
