The Coin Flip Simulator is an interesting electronic project which can be used to conduct a toss between two teams or individuals. It is a decision maker used [[wysiwyg_imageupload::]]at the places where someone is not able to make up the mind. When a button is pressed, the head and tail LEDs start flashing alternatively at a high speed. The speed slows down and it finally stops with only one LED glowing which determines the final result. In this project 555 timer is wired in astable mode. 7473 IC contains two independent positive pulse triggered J-K flip-flops with complementary outputs. When the clock is LOW, no output is received. When clock is at positive transition, the data from J and K gets transferred from slave to the master. When the clock is at HIGH the J and K inputs become disabled and with negative transition the data from the master gets transferred to the slave.
