I want to build a propeller clock using ATMega 16 . Does anyone have a schematic file for this king of project?
I want also to use 3 74hc59581 latches for my Rgb Leds and i also need some help with the code. If anybody has done this , please share

yes
im working on the same project
first i made it with 8051 later i developed it with atmega16L
currently im working to stebilize the display using a IR slot sensor and interrupts of atmega16,
if you want to make a simple one
you need to work on delay calculations as per your motor.use the delay functions given in util folder in winavr
#define F_CPU 16000000UL
// as per your working frequency
#include<util/delay.h>
the functions are
_delay_ms(1000);//1000milliseconds delay
_delay_us(1000);1000micro seconds delay

Thank you for the advice . I've read your blog and it hink you did a great job .
I also read the comments , you offered the code in C . Could you please send it to me on my email dj_petri_91@yahoo.com?
Have you used the IR emitter to activate the main interuption ( when the propeller completes a full rotation)?
Thank you again

if we use IR led and photodiode the switching will not be accurate. and it wont work properly at high speeds
