Introduction: 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!
