Re: A Newbie Needs Help
Thank You For Your Reply
I Dont Need To Use sensors at my project as they allowed us to simulate sensor pulses with push buttons , and the 1st link you supplied is a much bigger project than mine , all i need is this :
2 seven segments display one of the cars inside and one of the free spaces , in short .. all i need is a ciruit that decrements a seven segment display and increments another one each time i push a button so that the 2 numbers displayed are always of the same sum , and the process is reversable (for the exit gate sensor button).
i aint trying to cheat i just want someone who knows this stuff to tell me what to do and how to make it work and i will work hard in it , besides it wouldnt hurt if i found a simmilar project so that i can learn from it , i have very little time to deliver and i also have finals in less than a month.
much thanks
