    No cuts today.
    Driver board design for the 5 x engine shed linear actuators with one limit switche input each and 3 outputs to drive relays for Thomas, Harold and the Fat Controller motors.
    The two limit switches on each actuator will be wired in parallel to reduce the number of data pins required as this uses all but pin 1 the Tx pin.
    The big black block is an Arduino Leonardo.
    Cheers Trev
    P.S. I now have two 3d printed buildings, one to cover each flipper switch.

    New lower profile linear actuators with adjustable switch positioning. I needed a bit more clearance underneath so I moved the micro switches to the side and reduced the height by 5mm. I also needed to be able to adjust the position of the switches to allow all the trains to stop in the same place. The mounting rods for the engines are in different places so I need to move the switches for each engine.
