Hello all, Thought I would introduce my self.. I live in las vegas and have always been into electronics.. I won 1st place in the 5th and 6th grade science fairs for building electronic circuits.. Anyways my hobby has been lately is drag racing (I know has nothing to do with electronics) But what I am trying to make is a Automatic transmission controller.. Basically after doing quite a bit of research I have found that I would need to use a 2 bit synchronous (did I spell that right?) counter that will control relays that send voltage to two solenoids.. This will allow me to up shift/downshift the transmission via button's..
Here is how the two solenoids control the transmission and corresponding gears
UP SHIFT S 1 S 2
1st Gear ON OFF
2nd Gear ON ON
3rd Gear OFF ON
4th Gear OFF OFF
So if I can build a circuit that can output voltage on certain pins of a IC that would hook up to the relays and send voltage to correspond with the push button.. Its easier if you think of the solenoids as lights I guess.. It would also have to be able to count down in the opposite order of counting up.. Hope you can understand what Im talking about..
