Coordinated motion

Two motors sweep in unison using a Pardalote group. Each motor's type — PWM servo, serial bus servo, or stepper — is chosen independently from the popup under its dial, so the pair can be mixed (the default is a servo + a stepper). Both motors ping-pong between two positions, arriving together on every leg. Each dial visualises the motion — a 180° gauge for PWM servos, a 360° dial for bus servos and steppers.

This is the p5.js demonstration of group.writeTimed() / whenDone(): one call moves both motors, and each motor type reaches its target its own way (bus servos via matched-speed SyncWrite, PWM servos via on-board interpolation, steppers via a board-timed constant-speed move) — all in one WebSocket message.

Hardware

Any Pardalote board (UNO R4 WiFi or ESP32) plus two motors of any type:

The Arduino sketch just needs the matching extension(s) included — the simplest is to include all three so you can switch type without re-flashing:

#include <Pardalote.h>
#include <PardaloteServo.h>
#include <PardaloteBusServo.h>
#include <PardaloteStepper.h>

void setup() { Pardalote.begin(); }
void loop()  { Pardalote.run();   }

Browser

This is a tool — it works out of the box, no code editing:

1. Open index.html in a browser.
2. Type the board's IP into the field at the top and press Connect.
3. Pick each motor's type from the popup under its dial and set its pin(s) (or bus ID) in the fields below — changes rebuild the group and reconnect.

The browser remembers the IP, motor types, and pins for next time. Without a connection the dials still preview the sweep.

Notes

• The dials animate a display interpolation of the commanded sweep, so they move smoothly even before the board connects (you'll see status: reconnecting… until it does). The feedback readout shows each motor's real position once polling returns values (bus servo / stepper).
• The sweep starts each leg from the last commanded position, so the motors are snapped to the low pose once on connect (group.write) to establish a known start — see the note on first moves in the Groups docs.
• Edit the low / high values in TYPES to change each type's sweep range.
