1. Automated train station

2. Introduction My project is about a automated railway system.The basic idea is to use the Grove kit to determine the time,to play the corresponding sound when a train reaches the station, and to know when the train reaches the crossover.

3. Parts used from Grove kit: – Seeedduino v.2.21(Atmega 168p) – Stem Base shield – Twig OLED display – Twig RTC – Twig Sound recorder – Twig sound sensor – Twig RGB LED – Twig buzzer – Twig motion sensor – Universal 4 pin cable other parts: – 125KHz RFID reader v0.9b from seeedstudio – 2x RF tags – breadboard – servo motor – train kit

13. The crossover(1): The PIR motion sensor detects the train, sends this information to the arduino and the microcontroller activates the red light on the LED, starts the buzzer and lets the barrier down with the help of the servo motor

14. The crossover(2): When there is no motion the led is green, the buzzer is off and the barrier is up. The demo code will be in crossover.txt

15. RF ID This part is used to identify the trains. Because there are 2 trains there was a need to add something unique to each train. I used 2 rf tags on the train and in the station an RF ID. When the tag changes the sound recorder will know and play a different message in the station. Demo code will be in rfid.txt

17. Time and date: The most important element in a station is of course the time. The RTC is providing this information to the OLED. Demo code in rtc_oled.txt
