Title: Different kind of clock
Post by: klayus on Apr 19, 2011, 07:18 pm
here is my first arduino project :)
it's a watch that uses 2 servos to indicate the hour and minute while an 16x2 lcd prints the date, day of the week and the temp
i used atmega168, 9g servos, ds18b20, ds1307, ds32khz a fotoresistor and a 3w blue led which is not yet in the pictures.

a couple of pics with it almost finished and i think finished

the code is attached in a txt document as i cant write more that 9500 characters

it runs for 2 days and hasnt lost one minute
very proud of it myself :D

Interesting but there is something wrong with the link to the zip file with the pictures.

Cool. I wonder if you would also make a complementary clock where the clock arms are always fixed while the clock plates rotate. Easier to read that way.

i kinda doubt it would be easier to read that way :) if you plan to do the watch you're talking about i would be happy to help!
best regards

I would make a fixed hand and the tip of the hand is a black square frame so whatever goes underneath it is kind of boxed. The minutes only increments once a minute instead of running constantly  :)

I'll make it my first motor project once I gather enough stuff to do a stepper motor project. I'll be asking you some questions. Thanks.
