Lunchtime Clock

Step 8 Put it all together

Once programmed, transfer your ATMEGA168 chip from the Arduino to your circuit board.

Plug in your RTC board into the socket. Make sure the pins are lined up correctly before powering it up.

Attach your circuit board and battery to the back of the clock. In true last-minute DIY fashion, I used hot glue and gaffers tape to do this. Self-adhesive Velcro would be ideal.
