# clementine clock
this is an orange/mandarin-themed clock to set timers & alarms for my room. I decided to make a clock because I usually don't have access
to my phone when I go to sleep at school, and I needed an easy way to know the time and to wake up at the right time. I chose a clementine
theme because I like oranges.
on the main PCB board, there is a 4-digit 7-segment LCD display (showing the time), a small button, and a speaker. there is also wires on the
main PCB board connecting a rotary encoder (adjusting the time) on the top of the orange, a 3 AA battery case, and a big button (snooze & stop) at the
"stem" of the clementine. the case is a 3D-printed cylindrical clementine case.
