Main Idea

The idea to implement a simple controlling circuit, using a TI Innovator in a vivid and close to real life example. Pedestrian lights that operate temporarily when necessary should be installed at a pedestrian crossing. The traffic lights should switch to the red light and after actuating a switch, subsequently to the green light again.


  • The traffic lights are simulated with simple LED lamps.
  • The trigger signal for changing the light is tripped by a switch
  • The program is required to work continuously, a brightness sensor is used to stop the process.
