Hooking up the RFID-RC522 to the Arduino Leonardo
My initial trial with the RFID reader was with the library from https://github.com/miguelbalboa/rfid. I then switched over to the https://github.com/ljos/MFRC522 library as its code looks cleaner. The pin layout for the Leonardo was not given and it took me some time to figure it out. So here it is:

Arduino Pedestrian Traffic Light
Just for fun I programmed and build a pedestrian traffic light with the Arduino Leonardo from Borderless Electronics.
The v1.0 loops through the traffic light pattern continuously. With the v2.0 I added a pedestrian push button and an audible alert for pedestrians. Below is a video of the final result.
Detailed information, the Arduino program and building instructions can be found on Github.
