Analog-JST Board

Wiring and programming

Overview

The Axon Servo Analog-JST Board allows you to wire the analog output from "+" series servos without the need for custom wiring/adapters. Simply plug in the 3-pin analog output connector from up to two servos into the back of the board, and a 4 pin JST-PH wire from the front of the board to either of the analog ports on the REV Robotics Control or Expansion Hubs.

Code for getting the position of + series servos

//get our analog input from the hardwareMap
AnalogInput analogInput = hardwareMap.get(AnalogInput.class, "myanaloginput");

// get the voltage of our analog line
// divide by 3.3 (the max voltage) to get a value between 0 and 1
// multiply by 360 to convert it to 0 to 360 degrees
double position = analogInput.getVoltage() / 3.3 * 360;
