Pedestrian crossing traffic light control system using AVR Register level programming 🚥🚦

This project totally done as a Simulation using Proteus 8 Professional software. Also I used Arduino UNO board plugin for add Virtual arduino bard. As the Microcontroller Atmel ATMega328p 8bit AVR Microcontroller used.

Fatures

• Accurate 1Hz delay
• 8 Seven segment displays
• Two Push buttons

How it work

When You press push button for corssing. 30 seconds countdown start for vehicles. After this 10s countdown start for Pedestrian

Used Technologies

• Timer1 (16 bit timer TCNT1) used as the timer
• As the pre scaler 1024
• To call interupt Timer1_OVF_vect used
• INT0, INT1 registers used for External interupts
