Button and Clock issues

so making cactus babysitter few things.

1. leaves fluorescent light on hour hour. uses realtime clock , relay.

2. pumps water vase watering system every sunday @ noon calculated amount of time rough amount of milliliters per plant needed. uses realtime clock, pump , relay.

3. has 2 rgb lights vary depending on desired temp. (both green if good, 1 or 2 blue if cold, , 1 or 2 red if hot)

4. has lcd screen display variables (time light on, time light off, milliliters, , desired temp)

5. has 4 buttons used change these variables on go (time light on, time light off, milliliters, , desired temp)


so works right except 2 things.

• buttons not change variables should. if press in button, turns off (lcd, leds, arduino leds, relay leds) release button , code resets. it's bizarre , don't know what's wrong. believe wiring right wrong. wiring complicated wanted avoid having post if obvious coding issue.

• clock randomly resets 1/1/2000 -- 00:00:00. last night had big light working @ 1am, programmed turn on @ 1am, @ 7:20am light turned on again, meaning clock reset hour earlier this. checked code morning , sure enough clock reset few hours ago. i'm not sure why going on either. 2 problems may related.


any insight guys provide awesome.

***note*** removed debugging serial code, rgb code, , lcd code able fit in 1 post.

also looks rgb values wrong wired them wrong gives correct colors.
