Traffic Light Controller with Pedestrian crossing

Man and movement 

The first Traffic lights were installed outside the Palace of Westminster London on 10th December 1868 to control the increasing number of vehicles there. However, according to some sources, the Traffic lights controller later exploded and injured the policeman operating it [1]. This Traffic Light design was adapted for controlling movement of vehicles and pedestrians at a critical busy junction. 

Digital Clock Design using DS1337 RTC

Clock Display / Real Time Clock

Digital clock is increasingly integrated in many modern electronic devices and applications due to the importance of time keeping. In this post, a digital clock was designed such that the time was derived from a Real Time Clock controlled with a microcontroller over I2C interface.
