Clock example example (Extended class example)
|
||
|
|
|
||
|
|
Display a clock on the display. For this demo you can add a speed multiplier to make the clock run faster. For a real clock you want to use a delay of 1 min or even use a Real Time Clock module (RTC)
|
||
|
|
|
||
|
|
The circuit:
|
||
|
|
* connect TM1637 pin CLK to Arduino pin D4
|
||
|
|
* connect TM1637 pin DIO to Arduino pin D5
|
||
|
|
* connect TM1637 pin Vcc to Arduino pin 5V
|
||
|
|
* connect TM1637 pin GND to Arduino pin GND
|
