Smart LED Clock

How to install

Login to your Raspberry Pi and stay in the home directory.

git clone https://github.com/bennysp/smartledclock.git
cd smartledclock
chmod 755 install_smartledclock.sh
./install_smartledclock.sh

If everything worked, then you should see a clock displayed on your LED panel!

Starting and Stopping

Setup installs to systemd. It will startup/shutdown via the OS reboots. If you want to startup and shutdown outside of the OS, you can use the standard commands.

sudo systemctl start smartledclock.service
sudo systemctl stop smartledclock.service
sudo systemctl status smartledclock.service
sudo systemctl restart smartledclock.service

Hardware used

• Raspberry Pi 2 B - Amazon Link
• Adafruit RGB HAT - Amazon Link
• 64x32 RGB LED Matrix - 3mm pitch - Adafruit Link
• 5v 10amp Power Supply - Amazon Link *Note at the time of this writing, I am only using the standard power supply for the Pi. This is enough to power the Pi and LED display with the standard red text, but probably won't work for white.

Development Language

• Uses C language - I am not very experienced in this language, but giving the performance concerns that have been listed with the library on Raspberr Pi, I am trying to continue the use of C.
• One very small shell script for calling clock functions and options.

Libraries

• Raspberry Pi RGB Matrix library - https://github.com/hzeller/rpi-rgb-led-matrix

Goals and Status

1. Display a simple clock on startup COMPLETE
2. Create layouts for placement
3. Create first app - weather?
4. Incorporate connections to IFTTT
5. Webserver for admin and management

Optional Goals

1. Mobile app
