The Rolls Royce of Arduino Controlled Model Railway Turntable Controller

Roy builds a custom controller for a customer, as usual in Roy’s eyes, a simple controller with switches to locate the alignment, Roy built a programmable controller, with seven push buttons, each with an led, and a stepper motor driver, as well as a potentiometer and a rotary encoder. As the Arduino Pro Micro does not have enough in/out pins to do all of this, Roy used a Resistor Ladder to read the Push buttons, this used 1 input instead of 7.

The Rotary encoder is used when programming the unit, while the potentiometer is used to set the speed of rotation of the potentiometer.

    nice work, have posted this blog on the N Gauge Forum’s website.

  2. Thank you Andy. This was a job to help one of customers. Design time of a few hours. We were thinking of playing around to make this DCC controlled which would vastly reduce the component count. Anyone interested?
