Let me state at the beginning that I’m not into electronics. I know a little but just enough to get me into trouble. My interest is in model railways. And I’d like to use servos to change the points/turnouts/switches (whatever you choose to call them) and change the polarity of the frog of the point.
I’ve been investigating methods for controlling servos and, after watching the Pololu video, this controller seems to be a good choice. I was concerned that the board would require a permanent connection to a PC to operate but I see that’s not so. I don’t want to end up spending more time programming and less time “playing with trains”. So I’m avoiding using an Arduino. Or a Raspberry Pi (I have an original).
I have 20 or so points to control and I’d like to do that by using a buttons to trigger the servo and leds to show the position of the point. The push buttons and leds will be mounted away from the board on the fascia near the point.
Unfortunately, the Pololu video didn’t show how to connect the buttons.
Am I going down the wrong track or is this something you can assist me with?
