Arduino Clock

Presentation

This project is as simple as his title, just a clock display on a 4 Digital 7 Segment Display. The hour can be change via a remote control.

Modules

• Arduino card with at least 9 pins
• 4 Digital 7 Segment Display
• RTC, in my case I use a DS1307
• IR receiver module
• Decoder (not essential but better to use less pins on arduino card), in my case I use a 74HC595 IC

Libraries

• IRremote.h

to manage the remote control

• Wire.h

allow you to communicate with SDA and SCL pins of the Arduino card (usefull for the RTC)

you can see the location of those pins here : https://www.arduino.cc/en/reference/wire

• DS1307.h

to create an instance of clock object to get the hour
