Archives - a project from primary school: Road intersection mockup

I made the project in the 3rd grade of primary school (2010) for technical laboratory. The aim of the project was to create an electronic mock-up of the road intersection, used while learning road traffic rules in technical lessons at school. The model presents a road intersection, which may include: tram (t), bicycle (r), car (s). Standing vehicles are displayed on displays built of red light-emitting diodes. Vehicle traffic is animated using intersecting LED lines. Each road is marked with a road sign indicated by a glowing diode. The mock-up is connected through the RS232 port with a computer. It is used to select previously defined road situations or to design new ones. The project based on ATMEGA32 microcontroller.
