Traffic Light Controller By Using Arduino Kit

Project Description

Traffic light controller helps to manage the traffic and to maintain proper traffic management. These systems are placed at the intersections of the road or at the crossings to avoid congestions and accidents. The systems indicate to the driver by using different colors of light. Therefore, it is simple to avoid congestion at the intersections.

Pin Connection

• Connect all LED’s GND pin to GND through 220ohm resistors
• Connect 1^st Red LED +ve pin to Arduino pin 8
• Connect 2^nd Red LED +ve pin to Arduino pin 5
• Connect 3^rd Red LED +ve pin to Arduino pin 2
• Connect 1^st yellow LED +ve pin to Arduino pin 9
• Connect 2^nd yellow LED +ve pin to Arduino pin 6
• Connect 3^rd yellow LED +ve pin to Arduino pin 3
• Connect 1^st Green LED +ve pin to Arduino pin 10
• Connect 2^nd Green LED +ve pin to Arduino pin 7
• Connect 3^rd Green LED +ve pin to Arduino pin 4
