Lets start with some background. I want to have a robot that automates all combinations between 0000 - 9999. what i want it to accomplish is a machine that can find certain combinations on a hand held GPS system. the easiest way i can see it working is having solenoids for the individual numbers 0-9. and maybe 1 more to aknowledge the current combination entered.
the parameters are 4 digits 0000-9999. what i want to accomplish is i want to assign individual pins/solenoid to a specific number. (example, pin 3 = the digit 4, pin 5 = the digit 9 etc...)
so when the running count is 0012, i want the Solenoid that i designate for "0" to activate twice, the one i designate "1" to activate once, the solenoid i designate 2 to light up once in that order. i want that to continue until the count reaches 9999 then terminate.
Here is a video of what i want accomplished.
