Arduino Clock
Intro: Arduino Clock
Here we will show you how to make a clock out of an arduino!
STEP 1: Materials
Arduino Genuino UNO
Jumper Wires
Breadboard
Seven Segment Display
Code https://github.com/joonyeechuah/digital_clock/blob...
Box
STEP 2: Pins
Connect the following pins using jumper wires to the 7 segment display:
d1- 13
d2 -11
d3 -12
d4 -10
a -9
b -8
c -7
d -6
e -5
f -4
g -3
dp -2
HOUR_BUTTON -A0
TICK_LENGTH -250
STEP 3: Breadboard
Use the mapping of the breadboard to build your own breadboard.
Key:
White (wire) (left most) = GND
Blue = 3
Green = 2
STEP 4: Code
Upload the code from https://github.com/joonyeechuah/digital_clock/blob...
to the Arduino
STEP 5: Finishing Up
All you need to do now is add a portable battery, and your'e finished!

Very nice work. Is this your first Instructable? Arduino based clocks really are high in digabilty. Only suggestion I would make would be to a link to the 7 segment display library in the tutorial. I'm looking forward to your next tutorial and of course the one after that and so on. Thanks for putting this up.
