# Feature Overview
## Direct Control Mode
The direct control function does not require programming; actuators can be easily controlled via the hub. Users can directly operate actuators connected to different ports by using the up, down, left, and right buttons. Ports 2, 4, 6, and 8 can connect various actuators, offering convenient operation.
### The Hub Controls Servo Motor
|  |  |
| --- | --- |
| Motor connected to Ports 2 and 4:
+ **Up button:** Controls motor reverse rotation.
+ **Down button: **Controls the motor's clockwise rotation. | Motor connected to Ports 6 and 8:
+ **Left button:** Controls motor reverse rotation.
+ **Right button:** Controls the motor's clockwise rotation. |
### The Hub Controls Touch Color LED Sensor
|  |  |
| --- | --- |
| LED connected to Ports 2 and 4:
**Up or Down button:** Toggles the LED module on or off. | LED connected to Ports 6 and 8:
+ **Left or Right button:** Toggles the LED module on or off. |
## Logic Control Mode
The logic control function requires no programming and allows actuators to be controlled effortlessly through various sensors. In this mode, input and output devices must be connected to paired symmetrical ports (e.g., Port 1 for input and Port 2 for output, or vice versa).
### Encoder Sensor
|  |  |
| --- | --- |
| Clockwise rotation: Controls the servo motor's forward rotation.
Counterclockwise rotation: Controls the servo motor's reverse rotation.
Rotation angle: Adjusts the servo motor's speed.
Button press: Stops the servo motor. | Button press: Toggles the LED module on/off. In the "light on" state:
+ Clockwise rotation increases LED brightness.
+ Counterclockwise rotation decreases LED brightness. |
### Gyroscope Sensor
|  |  |
| --- | --- |
| Horizontal position: Stops the servo motor.
Tilting forward: Controls forward motor rotation.
Tilting backward: Controls reverse motor rotation.
Tilt angle: Adjusts motor speed (greater tilt = higher speed).
Forward/backward tilt: Adjusts LED brightness (greater tilt = brighter LED). | Forward/backward tilt: Adjusts LED brightness (greater tilt = brighter LED). |
### Distance Sensor
|  |  |
| --- | --- |
| Detects object proximity to control motor speed and direction.
Closer objects: Faster motor speed, clockwise rotation. | By detecting the distance, you can control the brightness of the color LED sensor, the closer the distance, the higher the brightness. |
### Sound Sensor
|  |  |
| --- | --- |
| Detects sound to trigger:
Servo motor: Rotates clockwise for 1s. | Detects sound to trigger:
LED sensor: Lights up for 5s. |
### Multifunction Gesture Recognition Sensor
|  |  |
| --- | --- |
| Controls Servo Motor:
Left-to-right gesture: Clockwise rotation.
Right-to-left gesture: Counterclockwise rotation.
Upward/downward gesture: Stops the motor. | Controls LED Sensor:
Left-to-right gesture: Turns the LED on.
Right-to-left gesture: Turns the LED off.
Downward gesture: Turns the LED on.
Upward gesture: Turns the LED off. |
## Logic Restriction Mode
This mode disables all intelligent functions (direct and logic control), leaving only basic hardware capabilities. It is useful for limiting device behavior, hardware testing, or specific use cases.
**Activation:**
+ Press and hold the “Power Button,” then press the “Down Button.” A purple breathing light indicates successful activation.
**Deactivation:**
+ Press and hold the “Power Button,” then press the “Down Button” again.
Activation and deactivation require holding the buttons for over 3s. Otherwise, the device will shut down, exiting the mode automatically.
