Instructions

The program
11fussgaengerblau
controls a pedestrian light
with a flash
12. Day
Pedestrian traffic light with red/green traffic light
The experiment of the 12th day is another version of the pedestrian traffic light, but the RGB-LED now shows red or green to the pedestrians.
Components: 1 x plug board, 1 x LED red, 1 x LED yellow, 1 x LED green,1 x RGB LED, 5 x 220-Ohm
resistor, 1 x button, 1 x wire bridge, 7 x connection cables
The program
The program runs similarly to the previous version, but will initially additionally switch on the GPIO-pin to which the red colour of the RGB-LED
is connected. After the traffic light has switched to red, the red colour of the RGB-LED is switched off for 2 seconds at the GPIO-pin 15, and the
green colour of the RGB-LED at the GPIO-pin 18 is switched on.
