ABSTRACT The ,oal of this project was to create a 3di#ital coin tosser4 that randomly displays 55h55-*")%/ and 55t55-T).6%/. ) button is held to be#in the roll$ and then$ after the button is released$ the head and tail h and t respectively displays on 7 se#ment display.)n important feature of this circuit is usin# a seven se#ment cathode 6" display.The end result is a di#ital die that rolls and displays either the 55h-*")%/ or 55t-T).6%/.This circuit is operated by touchin# the push button..t is very difficult to predict which 6" will remain illuminated.TABLE OF CONTENTTitle pa#e8888888888888888888888888888. !ertification888888888888888888888888888.iedication8888888888888888888888888888ii)cknowled#ement 888888888888888888888888..iiiTable of content88888888888888888888888888 iv)bstract8888888888888888888888.888888 vCHAPTER ONE1.0INTRODUCTION1.1 &reamble1.9 )ims and objectives 1.3 "conomics importance of the study1.: Terms of efinitionCHAPTER TWO2.0LITERATURE RE%IEW9.1 !apacitors9.9 %emiconductor9.3 .nte#rated circuit9.: Push switch2.5 0esistor9.; %witch9.7 %even
