- 🔴 Red LED: actuator position state

- 🟡 Yellow LED: local object detection

- 🔵 Blue LED: remote device's object detection

This section simulates the movement of an object on a seesaw using linear actuators, following gravity principles.

- ● ● / ○ ○ —> Both sides same state: Move to middle position (totalLength/2)

- ● ○ —> Object in Device 1 only: Device 1 extends, Device 2 retracts

- ○ ● —> Object in Device 2 only: Device 1 retracts, Device 2 extends

- Communication via Particle.publish() and Particle.subscribe()

- Device 1 broadcasts "doBlue_1" events

- Device 2 broadcasts "doBlue_2" events

- Each device updates state based on partner events

Linear actuators can control direction, speed, and timing, but we aim to use them to achieve different positions in three modes to simulate seesaw movement. Here is our strategies:

- Position tracking using time-based calculations and movement calculations based on speed

- Movement functions: extend, retract, stop, and moveToPosition(int targetPosition)
