This circuit for a digital clock with date and temp.

i need someone to tell me what are the components in this photo,
and tell me where do the end of the floating things go ??

is it to buttons or to V or to Ground

plz soo important

hent : things he use are :-
pic microcontroller, the DS18S20/DS18B20 sensor, 4x7 segments (common anode, something like KW4-301xxx Series, or common cathode something like CC56-21SURKWA), four transistors, some rezistors!

The arrows marked 5V go to 5V which the arrows marked 3V go to 3V. The arrows marked +5V/+3V can either connect to the 5V or 3V supply. To be on the safe side, just connect them to the 3V supply. The GND is the ground (no arrow--just a line).

The circuit will need the firmware program loaded so that it works.

Good Luck.

I think the +5V/+3V ones are all connected together.

+3V goes to battery cell.

+5V goes to external 5 volt power source.
