servotest.js

JavaScript
Run the servos with MATRIX Lite! Save this into your lite-js folder, then run "node servotest.js" and watch it go! (You can also substitute in other values, to test the limits of your servos.)
const matrix = require("@matrix-io/matrix-lite");

matrix.gpio.setFunction(0, "PWM");
matrix.gpio.setFunction(1, "PWM");

matrix.gpio.setMode(0, "output");
matrix.gpio.setMode(1, "output");

matrix.gpio.setServoAngle({
  pin: 0,
  angle: 90,
  min_pulse_ms: 0.8
});

matrix.gpio.setServoAngle({
  pin: 1,
  angle: 90,
  min_pulse_ms: 0.8
});
