Hi all,
I am trying to come up with a circuit to manually control my automatic gearbox on a 4x4.
The gearbox has two solenoids to select the gear. I shall refer to them as S1 and S2.
In 1st gear S1=on S2=off
2nd gear S1=on S2=on
3rd gear S1=off S2=on
4th gear S1=off S2=off
i understand the order is decimal 2,3,1,0
(or if we swap S1 and S2 over 1,3,2,0)
i have identified this as a kind of 2 bit binary counting.
What i am looking for is a simple circuit which has 2 momentary switch inputs, one to count up, and one to count down. The circuit also needs 2 relay outputs which i can then use to control the solenoids.
In an ideal world a seven segment display showing the gear would be brilliant.
I understand this is easy to achieve with a PIC but i have very limited programming experience and no equipment for this, i do however have a basic grasp of electronics.
Any help would be much apreciated
Thanks in Advance
