Signals and servos controlled by an Arduino Nano | Modelling a GWR branch line | Episode 16

After a little track weathering, it's time to install some motorised signals for the model railway. Here's what I used: * Arduino Nano v3 * PCA9685 servo driver board * Arduino Nano expansion board * SPST switches * Ratio GWR signals kit * 9g servos * Servo extension cables * AdaFruit servo driver library https://github.com/adafruit/Adafruit-PWM-Servo-Driver-Library * Easing library https://www.arduino.cc/reference/en/libraries/easing/ * easings.net * PointsController Github repo https://github.com/mafu-d/arduino-points-controller Frontington and Backwoods is (or will be) a OO gauge model railway layout, depicting a fictional GWR branch line terminus, set in the rolling South Devon countryside not too far from Kingsbridge, at some point probably in the late 1930s.
