    Ok thanks for reading this. I am planning to make a automated control system for a gehl baler. I have an articulating dc 12v motor on the baler, and that is controlled by a TL494 PWM IC. The operator has a switch to activate the motor, a latching dpdt on-off-on (i believe) switch that reverses the polarity for the motor labeled Forward and Reverse. I plan on attaching my schematic i made to the Reverse pole in the switch.

    My PCB as of right now.

    Now i need to get a counter for how many bales are made. I want to have two buttons that need to be pressed at the same time in order for it to reset back to zero. I would like it to use a magnetic switch to trigger the count. I have 2 555 timers in my box of stuff if those will work. This will be always connected to a line of 12v dc (tractor battery). it has to be three 7-segment displays to show 000-999. It would would be great to have the hundred's and ten's place on the counter not light up till the have at least a value of 1. But that's not necessary.

    Summary:
    Power: 12v DC OR 24v dc
    Input: Reed Switch, Reset
    Output: three 7-segment displays
    Objective: Reed switch completes circuit> sends pulse to decoder> Displays current count on displays>>Reset to zero<<>>Begin again

    Once you post your schematic we maybe able to help you more.

    Eagle has a schematic capture program.

    You managed to draw a PCB quite well. Surely you can do the same for a schematic.

    Your PCB looks like ExpressPCB. Just use their Schematic program. It's usually done the other way around...Schematic > PCB
